The butter to buy? It's the golden glory that Hope Creamery czar Victor Mrotz crafts specifically for Heartland Restaurant & Farm Direct Market, a premium product with an 85 percent butterfat content, which is several percentage points higher than the creamery's widely distributed butter. Mrotz's finest clocks in at $7 per wax paper-wrapped pound, but as one of the state's great dairy products — that crucial extra butterfat is culled from pasture-raised southeastern Minnesota cows — it more than commands its premium price.
