I love Marzipan, Thank you.There are two ways of making it: One is cooked marzipan, and the other is uncooked. Some recipes have egg whites, but the one that I use doesn't.
The recipe that I use is:
1 cup ground almonds
2 cups powdered sugar
1 tablespoon light corn syrup
1/4 teaspoon almond extract
1/4 teaspoon vanilla extract
1 to 2 tablespoons water
Work everything except for the water together in a bowl until there are no large lumps, and then gradually work in 1 to 2 tablespoon of water with your hands until the mixture can be formed into a ball. It's a bit hard to describe the texture, but I'll try: It should be workable like fondant, but somewhat sticky -- not dry or crumbly. You should be able to roll it out between two sheets of waxed paper, and it should hold its shape when formed.
Wrap in plastic wrap or place in a ziplock bag and store in the fridge.
