Reheating Hollandaise or BĂ©arnaise sauce?

Never microwave! These are fragile emulsions and will split. Reheat by gently whisking over a double boiler on low heat. If the emulsion begins to split, try whisking in a spoonful of warm water, never add more butter. 

Dry roast chicken?

Avoid a dry chicken by stuffing some flavoured butter under the skin before roasting. Simply ease your fingers under the skin of the chicken breast to create a pocket (without breaking through) and fill it with softened flavoured butter. The butter bastes and flavours the chicken as it cooks leaving you with a moist and tender roast!
