For best flavor, let the dip rest even longer—up to a few hours or overnight—so the dried onions fully soften and season the sour cream; use full-fat sour cream and mayonnaise for a richer, creamier texture, and if the dip thickens too much in the fridge, loosen it with a tablespoon of milk or cream at a time. You can customize the flavor by adding a dash of hot sauce, smoked paprika, or Worcestershire sauce, and make it ahead for parties since it keeps well in the refrigerator for up to 3–4 days in a tightly sealed container. Always taste and season after chilling, as flavors will mellow, and remember to keep the dip cold when serving, especially at gatherings, by placing the bowl over a slightly larger bowl filled with ice.
