Smart Cooking Tip of the Issue:

Do not put anything acidic (tomato/ tomato products, lemon juice, vinegar etc) at the beginning, when cooking vegetables, specially potatoes. This helps to tenderize the vegetables quickly otherwise it takes longer cooking time & have lesser nutritive value. You can add acidic condiments during the last stages of cooking.
