Mustard (condiment) tradition of mustard making, Dijon is regarded as the mustard capital of the world. The early use of mustard as a condiment in England is attested from the year 1390 in the book "The Forme of Cury" which was written by King Richard II's master cooks. It was prepared in the form of mustard balls—coarse-ground mustard seed combined with flour and cinnamon, moistened, rolled into balls, and dried—which were easily stored and combined with vinegar or wine to make mustard paste as needed. The town of Tewkesbury was well known for its high-quality mustard balls, originally made with ground mustard
Pressure cooking and some other foods like sponge puddings and Christmas puddings are typically timed according to their weight. Frozen foods need extra cooking time to allow for thawing. When pressure cooking at 1 bar/15 psi (gauge), approximate cooking times are one minute for shredded cabbage, seven minutes for boiled potatoes (if cut small, not diced) and three minutes for fresh green beans. If the pressure is released naturally after timing "(see Pressure release methods for details)," cooking times are even shorter. Food cooks more quickly when cut into smaller pieces. Some recipes may require cooking at lower than 1 bar/15 psi
