America's homegrown dressing; ranch style salad dressing is lower in fat than most, as it uses buttermilk for flavor and body. Ranch style dressing is also excellent for fresh vegetable dip, or sprinkled on baked chicken or fish, 1-2 tsp. per lb. To make 1 Cup dressing, mix 1 TB. seasoning in 1 TB. water, let stand five minutes, then whisk with ½ Cup buttermilk and ½ Cup mayonnaise. Also excellent as a fresh vegetable dip. For a lower calorie version use low-fat mayonnaise, or up the proportion of buttermilk, which will make the dressing thinner, but equally tasty. Ranch dressing should be refrigerated, check the freshness date on the buttermilk carton, and write it on the dressing bottle. Hand-mixed from: salt, bell peppers, garlic, onion, sugar, black pepper, parsley, thyme, basil.
