This is the very first recipe I learned to make all by myself, and, for a while, it was the only recipe I made regularly and with confidence. I still make it all the time, even though it can be a challenge to track down peanut butter in Hungary.
1 box cappellini (or spaghetti) pasta
1 cup peanut butter
1 cup water
4 tablespoons soy sauce
4 tablespoons sugar
3 cloves garlic, minced
2 teaspoons cider vinegar
1/2 teaspoon sesame oil
Cayenne pepper
Salt
Sesame seeds
First heat the water, then whisk it with the peanut butter until they are completely combined. Add soy sauce, sugar, garlic, vinegar,and sesame oil, mix well. Add salt and cayenne to taste.
Set salted and oiled water to boil. Cook pasta in boiling water until done. Drain and rinse in cold water until all the noodles are cold. Pour sauce onto noodles. Mix well. Sprinkle white sesame seeds on top.
