HuffPost consulted chefs, cheesemongers and cookbook authors about which grocery-store butters are worth buying, landing on cultured butter, made by fermenting cream with lactic bacteria before churning, as the superior choice over standard American sweet-cream butter.

Named favorites include Kerrygold and Vermont Creamery, with an assurance that checking a nutrition label and doing simple math can reveal a butter's true fat content.
