What was little miss muffet eating when the spider was sitting beside her?

Little Miss Muffet sat on a tuffet,

Eating her curds and wiegh,

Along came a spider who sat down beside her,

And frightened Miss Muffet away!

Curds are a dairy productobtained by coagulating milk in a process called curdling. Whey is the liquid remaining after milk has been curdled and strained. The whole mess is similar to cottage cheese.
