Churned fresh daily since 1911. Spreadable Challenge Butter with Canola Oil is soft right from the refrigerator, and perfect for spreading, baking, and cooking. It's soft because we've added canola oil, which is low in saturated and trans fats, and has no cholesterol, to our 100% pure creamery Challenge butter. Real challenge. Real difference. Farmer owned since 1911. From cows not treated with rBST (No significant difference has been shown between milk derived from rBST treated and non-rBST treated cows).
