Life is too short to eat margarine. Really and truly. One of my indulgences is to drop $3 for a brick of Somerdale English butter at Central Market. It’s too expensive to use for cooking, but spread it on bread and it will knock your socks off. It’s like tasting real farm eggs, or chicken that comes from an actual farm. For people raised on mass-produced food — which is to say, almost all of us — it’s like tasting the Platonic essence of the thing for the first time. If you’re me, there’s very little that can give so much pleasure for $3 than a block of English butter, which makes most commercially available American butters taste pale and watery.
