Book your group cooking class
Our private group, youth, and team-building cooking classes in Calgary are the perfect way to cook, laugh, and learn together. Led by Red Seal Chefs, our cooking classes welcome all ages and skill levels.
Organisms that cause food spoilage–moulds, yeasts and bacteria–are present everywhere in the air, soil and water. Enzymes that may cause undesirable changes in flavour, colour and texture are present in raw vegetables.
When vegetables are canned, they are heated hot enough and long enough to destroy spoilage organisms. This heating (or processing) also stops the action of enzymes.
Pressure canning is the only safe method of canning all vegetables (except tomatoes). Jars of food are placed in a pressure canner which is heated to a temperature of at least 240°F (116°C). This temperature can be reached only in a pressure canner.
