Use a pale-golden oil to make this silky, garlic-spiced mayonnaise. Nesting the mixing bowl on a tea towel fitted inside a stock pot creates an easy, even stabilization, which frees both your hands for simultaneous whisking and oil-pouring.
Ketchup made with roasted beets has a surprising, slightly earthy flavor—we love it in place of tomato ketchup on turkey burgers.

A splatter screen will help keep splashes contained while cooking the purée.
