Yummly’s technology and algorithms generate a profile of each recipe. This profile includes an analysis of the recipe’s ingredients, relevant diets, allergens, nutrition, as well as tastes – sweet, sour, bitter, salty, savory — and now, spicy. Hundreds of thousands of recipes are currently in its database, and users create preferences for the search through a lengthy “menu” of choices along a sliding scale, dialing things up, if you will, to your desired level. Spiciness is measured on the Scoville Scale, which ranks the heat of peppers from sweet bell peppers to through habanero chilies and beyond (U.S. Grade Pepper Spray-hot anyone?).
