Use whole milk ricotta: Whole milk ricotta gives the dip the best rich, creamy texture. Part-skim ricotta can work, but it may not blend quite as smooth.
Blend until fluffy: Let the food processor run long enough for the ricotta to become light and airy instead of just mixed.
Scrape down the sides: Stop and scrape the bowl as needed so the lemon, garlic, and salt get evenly blended throughout.
Taste before serving: Depending on the ricotta, you may want a little extra salt or lemon juice to brighten the flavor.
Serve chilled or cool: This whipped ricotta dip tastes best cold or slightly cool, especially if you are making it ahead.
