Notes: Sherry is a type of fortified wine originally from southern Spain. Don’t use the “cooking sherry” sold in many supermarkets–it can be surprisingly high in sodium. Instead, purchase dry sherry that’s sold with other fortified wines in your wine or liquor store.
Hoisin sauce is a dark brown, thick, spicy-sweet sauce made from soybeans and a complex mix of spices. Look for it in the Asian section of your supermarket and in Asian markets.
Seitan, a high-protein product made from wheat gluten, has a meaty texture and is found in health-food stores or large supermarkets near the tofu. The package weight varies, depending on whether water weight is included. Look for the “drained weight” on the label.
