Why do we buy pre-made salad dressing?

The longer I continue this clean eating experiment, the more mystified I am at our collective buying habits. This morning I made bleu cheese dressing and it took all of 3 minutes to whip up the batch. Why in the world did I ever buy the pre-made, highly processed, junk laden stuff before? There is absolutely no reason to buy the processed junk when it is so easy to make at home.

As you can see, my fridge currently contains 3 salad dressings, all homemade. The bleu cheese is in the large container at the rear. The other two are recipes already posted (buttermilk ranch and classic cobb dressing).



Bleu Cheese Dressing (makes approx 3 cups)

3/4 c mayonnaise
1/4 c milk (or half and half)
3/4 c sour cream
2 cloves garlic, crushed
1 T white wine vinegar
1 T dried parsley
1/4 t black pepper
1/2 t salt
6 oz crumbled bleu cheese

Add all ingredients, except cheese, to a bowl and whisk to combine. Add bleu cheese and toss gently. Pour into storage container and refrigerate until ready to use. Keeps up to 2 weeks in refrigerator.
