![]() ![]() Sodium carbonate: Sodium carbonate, Na2CO3, -also known as washing soda, soda ash and soda crystals, and in the monohydrate form as crystal carbonate- is the water-soluble sodium salt of carbonic acid. In cooking, it is sometimes used as an emulsifier and to prevent sticking, for example in nonstick cooking spray. Lecithin is sold as a food additive and dietary supplement. This results in a type of surfactant that usually is classified as amphipathic. In aqueous solution, its phospholipids can form either liposomes, bilayer sheets, micelles, or lamellar structures, depending on hydration and temperature. It has low solubility in water, but is an excellent emulsifier. It is usually available from sources such as soybeans, eggs, milk, marine sources, rapeseed, cottonseed, and sunflower. Lecithin can easily be extracted chemically using solvents such as hexane, ethanol, acetone, petroleum ether, benzene, etc., or extraction can be done mechanically. Gobley originally isolated lecithin from egg yolk-λέκιθος lekithos is "egg yolk" in Ancient Greek-and established the complete chemical formula of phosphatidylcholine in 1874 in between, he had demonstrated the presence of lecithin in a variety of biological matters, including venous blood, in human lungs, bile, human brain tissue, fish eggs, fish roe, and chicken and sheep brain. In 1850, he named the phosphatidylcholine lécithine. Makes 8 or 9 servings.Lecithin: Lecithin -UK:, US:, from the Greek lekithos, "egg yolk"- is a generic term to designate any group of yellow-brownish fatty substances occurring in animal and plant tissues, which are amphiphilic – they attract both water and fatty substances -and so are both hydrophilic and lipophilic-, and are used for smoothing food textures, dissolving powders -emulsifying-, homogenizing liquid mixtures, and repelling sticking materials.Lecithins are mixtures of glycerophospholipids including phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylserine, and phosphatidic acid.Lecithin was first isolated in 1845 by the French chemist and pharmacist Theodore Gobley. Remove from freezer about 10-15 minutes before serving. Drizzle with more chocolate or caramel syrup, if using. Drizzle chocolate and/or caramel syrup over the broken bar pieces, if using.Ĭover the second layer of cookies with the remaining Cool Whip and bar pieces. Cover Cool Whip with another layer of milk dipped cookies and half of the broken bar pieces. You will use about half the box to line the bottom of the dish.Ĭover cookies with half the Cool Whip. Line the bottom of an 8-inch square dish with the milk dipped cookies. Quickly dip the cookies, one at a time, in the milk. Today I used chocolate chip cookies because that's what was on sale and no one complains if I switch from the oatmeal to the chocolate chip cookies.ġ box oatmeal cookies, about 250g or approximately ½ lb (chocolate chip or coconut are good, too)Ģ small tubs Cool Whip or 1 large tub (about 4 cups)Ģ or 3 Skor or Crispie Crunch Bars, choppedĬhocolate or caramel syrup (optional, but good) They are hard, little crunchy things that soak up the milk like a sponge. Most of my friends and I make it with the inexpensive little Dare Breaktime Cookies or the no name generic brands that are similar. The original Snack-and-a-Half (both the ice cream treat and the dessert) uses oatmeal cookies but I've had it with chocolate chip and coconut cookies as well. Most people also sprinkle chopped candy bars between the layers, and I drizzle caramel and chocolate sauces in between as well as I think it adds a little bit of decadence to the dessert. Well, that would be the simplest form of the dessert. It's frozen for several hours and served still frozen or slightly thawed. This dessert uses oatmeal cookies layered between Cool Whip or other whipped topping, topped with chopped Crispy Crunch or Skor bars. I remember eating those as a kid but I don't think they make them anymore. I don't know who invented this dessert but I guess it was fashioned after the ice cream treat by the same name-two oatmeal cookies sandwiched together with vanilla ice cream and covered with chocolate. I made it this past weekend and took it to Peter's for dessert and sure enough I brought home an empty dish. It shows up when families gather or at church potlucks and I've never seen any leftovers unless it's a teeny, tiny gathering (2 people). Snack-and-a-Half frozen dessert is a well-known favourite among many Newfoundland families, including my own. ![]()
