From Spuds to Suds - A recipe for soap!


From Soup to soap, spuds to suds.. Just a few catch lines posted as a response to a photograph of home made soap I posted on my Instagram account.. Found it so appealing that I seriously started contemplating blogging about it. The decision was made when I got some fabulous feedback about the soap.

The idea of making soap crossed my mind during the time I dabbled in making Lip balm. A fellow Blogger friend, Nandita Iyer (Saffron Trail )had posted some ravishingly beautiful photographs of home made soap and it was sounded so fascinating that I immediately wanted to rush out and buy the ingredients right then and there.. Umm, not so fast - Inevitably the part about Caustic Lye and its corrosive properties followed and kind of slowed me down (actually stopped me). As a compromise I shopped for those bulk soap blocks from Michaels and tried to concoct my own 'flavors' and it was such a disappointing waste of time, money and effort. For one, those blocks have this long list of unpronounceable ingredients that immediately evokes the same disgust as reading a food label from prepackaged junk food.

And so, the idea got shelved until Caitlin Pike's tutorial on soapmaking from Food52, at which point any shred of resistance to lye dissolved (dare I say it?? like sudsy lather) and by the end of the week, I had already placed my orders for Lye, silicone soap molds, Almond oil, Shea butter (in lieu of Palm oil), as well as a base level immersion blender, Pyrex measuring cup, safety goggles and one of those supermarket bottom shelf enamel pots from the grocery store. 



Before you even begin, its absolutely essential to keep these soap making apparatus separate from anything you use in your kitchen. After you finish making a batch, rinse and keep these away in a corner out of reach and mind. Here's a list of the apparatus you need:

  • A big non reactive pot (5 quarts or more in size) - Avoid metals like aluminum and cast iron
  • A basic immersion blender (speeds up the mixing and saponification)
  • A pyrex measuring cup
  • A plastic bowl (Those take out plastic containers works well)
  • A silicone spatula
  • A knife or bench scraper for slicing
  • A spray container containing vinegar (to neutralize any lye spills)
  • Safety goggle & long rubber gloves (the ones you use for washing dishes)
  • A 9 x 5 loaf tin or silicone soap molds
  • Saran wrap or parchment paper for lining the loaf tin.
Instead of dedicating a weighing scale , I opted to wrap up my regular scale with plastic wrap prior to weighing the lye, and then carefully disposing of the plastic.


The chemical reaction is simple, The oils, aka fatty acids (also known as triglycerides) react with the lye to form a soap salt and glycerol (glycerin). In commercial soaps, much of the glycerol is extracted out, despite its moisturizing properties. Glycerin is a profitable by-product and the big industrial names are not going to waste it on moisturizing the hide of the general population!
Home made soaps tend to be uncomplicated. The moisturizing glycerin created by the saponification process stays in the soap and since the oils are known food grade ingredients you know what you're applying on your skin.

I made two batches of soap keeping the proportions from Caitlin's tutorial intact. Just played around with the proportions of the oils and the fragrances and the dried flowers added. The essential oils I had picked up from Mumbai Airport (T2) at the Forest Essentials outlet. If you get a chance do visit their store or website for some excellent High end skin care products, in particular the Madurai Jasmine range. Madurai is reputed for growing a unique strain of fragrant Sambac Jasmine that now commands its own geographical indication.


SO here goes, My first non edible recipe that smells delicious enough to eat!

Home made Soap:

Matcha & Madurai Jasmine Soap:

You need:

16 fl. oz Refined coconut oil
16 fl. oz shea butter
8 fl. oz almond oil
13 fl. oz Olive oil
19 fl. oz distilled water
201 grams Sodium Hydroxide (NaOH) crystals 
1 tablespoon Japanese Matcha tea powder
15 ml Jasmine essential oil
1 cup dried jasmine blossoms crushed lightly (optional)






Lavender & Tuberose Soap.

You need:
201 grams Sodium Hydroxide (NaOH) crystals 
28 oz refined coconut oil
8 oz almond oil
17 oz Olive oil
19 oz distilled water
1 cup dried lavender blossoms
15 ml Tuberose essential oil
10 ml Rosemary essential oil (I find the rosemary accentuates the lavender very well)
15 ml Lavender essential oil

Combine the oils in the non reactive pot and heat it to about 100 F. keep the pot on a  low heat to maintain the temperature while you prepare the lye solution.
Wear the gloves and the safety goggles and an apron for good measure.
Measure out the NaOH crystals in a plastic container and the distilled water in the Pyrex container. Its preferable to do this outside on the deck or in the garage, you need a well ventilated space to mix these ingredients. 
Slowly add the NaOH to the distilled water (NEVER EVER the other way around) and stir it with the silicone spatula until it dissolves. Caution: the liquid will begin to steam (temperature of about 200 F) and emit acrid fumes so keep your nose out of the way. Let this mixture cool to about 100 F.



Assemble the other materials such as the lined loaf tin, the silicone soap molds,  the essential oils, the dried & crushed blossoms.
Plug in the immersion blender. Gently dribble the lye solution slowly into the oil (which will begin to cloud up immediately), keeping the blender running until the mixture begins to thicken up.


The mix will continue to thicken in a manner reminiscent of custard. When the mix begins to leaves a light ripple on the surface, add the dried blossoms / Matcha tea powder. 


Continue to run the immersion blender while adding these. Soon enough the mixture will turn thick enough to leave a 'trace'  (when some of the thick solution is allowed to drip across the mix. it retains a distinct pattern over the surface for a couple of seconds before vanishing.   At this point add the essential oils into the mix and blend thoroughly.


Pour (or rather scrape ) the mixture out onto the prepped loaf tin / soap molds and smoothen the surface using the spatula. Carefully place away from general household traffic ina  quiet corner of the house to cool down and set for about 24 - 36 hours.
Then remove the chunk of soap out of the mold and cut into 1 inch thick slices. place on a drying rack in an airy location and allow to 'cure' for 3 - 4 weeks until the saponification process is complete, the water from the soap has completely evaporated and the soap has mellowed.


Wrap the bars in little wax paper bags and store away or share with friends and family.
each prescribed batch yields about 22 bars.



A little shout out to Bangalore based Delara Damania, the founder of Common Oxen, an eco friendly brand that specializes in (among other things) cold process soaps like the ones I made. I got these bars as a gift from my friend Akhila Seetaraman in Bangalore. Looking forward to trying these soaps out.





 For once, I sign off without the usual 'Bon Appetit'!!

Resolutions, part deux.

Some of us get to make resolutions not once, but twice every year. The first of course, on January 1st along with the rest of the world and the second time around, the last day of  the Indian festival of Navaratri, The 10th day that marks the end of the festival is known as Vijaya Dashami - the day when scores of kids , willing or not,  are marched off to commence music, dance classes or start learning to play an instrument.

Navratri, once you strip it of its patriarchal trappings, is an empowering festival celebrating the Mother Goddess. Each day, her various attributes (a daughter, a mother, a wife, a warrior, an intellectual,  as an unfettered free spirit etc.) are explored and worshiped. and thefood offering invariably is a protein rich Sundal made with various lentils - a meat substitute, a nod to a pre-Buddhist era when meat was an accepted part of Hinduism.



Back to the resolutions.. you'd have to have been living in a cave this past year not to have been made aware of how …

Aug 9 - Cauliflower Kolhapuri

I have a dear friend from school who lives in the City of Kolhapur in Maharashtra. When I visited her  at the gorgeous heritage resort she owns there en route to a holiday in Goa, she gifted me with a spice blend that I treasured to the last speck. It sat  at the bottom of my freezer and was doled out for special dishes just like Saffron is rationed out in many Indian homes. Its a lip smacking flaming  hot blend of onions, garlic and the famed Kolhapuri Mirch (red chili).

I marinaded cauliflower florets in a paste of this spice blend , salt and oil, and roasted it in a 450 F oven. Finished with a handful of green coriander berries, this was a fabulous treat paired with roomali roti.

Product Review: Ninja Mega Kitchen system and a recipe for Masala Dosa

One of the biggest reasons for attending conferences is the priceless experience of meeting fellow bloggers and get an invaluable exposure to all things  culinary. This includes vendors with new products to savor and get inspiration from.

I had no complaints about whatever appliances I had for making traditional Dosa (Traditional South Indian rice & lentil crepes) batter, a sturdy tabletop stone grinder that you could add the Urad dal, turn the timer on , and 30  minutes later, come back to a container full of fluffy, batter with the consistency of whipped egg whites. The
The cons of this is the cleaning up, of the various parts, the roller, the grinding bin, the multiple trays on which the rollers need to be placed while transferring the rice & lentil batter, the invariable drips of thick batter on the counter.... you get the point, It takes quite a bit of time.

I was pleasantly surprised when the appliance company, Ninja asked me if I'd like to try any of their appli…
