See how easy it is to prepare homemade dressings and mayonnaise.

Homemade dressings far outshine any store-bought varieties, and Martha will show you how easy it is to make your own. She starts the lesson with a delicious shallot vinaigrette prepared two ways: whisked directly in the bottom of a salad bowl and shaken in a small jar. She also makes a creamy blue cheese dressing — just the thing for drizzling onto a wedge of iceberg lettuce. And you can make your own mayonnaise, too. Follow Martha’s step-by-step instructions, then use it to prepare the most delectable BLT.
