Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and 43,450 recipes mention both. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Tomato Soup
Ingredients
Directions
Salt and pepper to taste. 1 tablespoonful flour.
Add the tomato, sugar, salt and pepper to the stock, let it cook one hour. With cold water make a thickening of the flour and add that, cook ten min- utes. Strain through a fine sieve. Just before serv- ing add one-fourth cup of cream, if liked. This is a great improvement.
