  • Mechanical Raising Agents
    • Air
      • It is a mixture of different gases
      • Put into the mixture in many ways
        • Sieving flour - air trapped between flour particles
        • Creaming fat and sugar together - air is trapped and held in place by egg which sets around the bubbles when the mixture is baked
        • Whisking whole eggs or egg whites with sugar - traps a lot of air in the egg protein
        • Folding and Rolling - traps air in layers which expand when baked
        • Rubbing in fat - traps some air
      • Used for cakes, biscuits, pastries, mousses, souffles, sponge puddings, sponge flans, swiss rolls etc.
    • Steam
      • Water Vapour
      • Used for mixtures that contain a lot of water like batters, choux pastry and puff pastry
      • The oven must be really hot and the door cannot be opened otherwise the mixture will collapse whilst baking
