Session 2: Lipids - Fats/Oils,phospholipds and emulsifiers) A natural follow up after the session on water, as oil doesn't mix with water (even a 3 yr old knows that). This was an opportunity to discuss triglycerides, alcohols, (carboxylic) acids and esters [briefly]. Saturated and unsaturated, cis and trans (and mechanism of hydrogenation – which explains why one gets trans fats) etc. Made butter, centrifuged milk,
Phospholipids and lecithin was discussed and used in making "airs" and then various chocolate chantillies

"Airs" that were made (see pics)
pineapple, watermelon, ginger beer, pomegranate, soy [+H2O; equal parts],
Honey [+H2O]; ginger beer, Raspberry syrup[+H2O], cranberry, lemonade, soy [+H2O; equal parts]
Wasabi peas with soy and ginger air

Chocolate Chantilly flavors made
Coffee, Coco-cola, Texas Pete hot sauce (+ H2O), sparkling mint, lemonade, raspberry (extract in H2O), ginger beer, watermelon, pomegranate, cranberry
I was quite amused that one group picked up the hot sauce to combine with the chocolate. It wasn't good because of the vinegar that was up front. The lemonade, coffee, ginger beer and watermelon were particularly good.
Chocolate Chantilly Base Recipe:
100g chocolate [good chocolate with only ingredients chocolate (or cocoa and cocoa butter/fat, sugar, lecithin]
95g water (or flavored liquid)
Melt chopped chocolate in hot liquid. Chill by putting bowl on ice and whisk vigorously to disperse water in the cocoa fat
Remove from ice when it starts to thicken. Whipp till soft peaks. Cautuion: this can thicken/harden rapidly
This is a 'fail-proof' dish
If it fails – heat, melt (add more chocolate or liquid if needed); repeat whisking on ice etc.
