It’s easier than you think.
The process of making mayonnaise is a basic emulsification (getting two things to mix that normally don’t), so it is a bit of a delicate process and time consuming; but the end result is so worth it.
When making ice cubes with items frozen inside (flowers, fruit, etc), to avoid cloudy ice, use distilled water -- boil and cool it first -- this will give you crystal clear ice cubes.
Weight and volume are two different things. If a recipe calls for "ounces," make sure you know whether it is fluid ounces or ounces by weight.
