Recipe Variations, Tips and Substitutions

• Potatoes – Each variety of potatoes contains different levels of starch content and will cook slightly differently. Adjust the boiling time as needed to adapt. You could also use Yukon Gold potatoes, white potatoes or red potatoes for this mashed potatoes recipe. Russet potatoes work best.
• Ranch Seasoning – Ranch dressing salad dressing mix is easy to find. If you buy it in a bulk container, you’ll need around 2 generous tablespoons.
• Begin with Cold Water – It’s important to start with cold water to boil the potatoes. Cover them leaving around 1-2 inches of head space.
• Garlic Salt – Normally I use plain salt to season potatoes but in this instance, garlic salt infuses the potatoes with more flavor. You could use plain table salt and granulated garlic or garlic powder instead.
• Don’t Overcook the Potatoes – Boil the potatoes just until fork-tender. They shouldn’t break into tiny pieces or be too mushy. Test the centers with the tip of a sharp knife or the tines of a fork. Cooking time may vary slightly depending on the size of the potato chunks.
• Drain the Potatoes Well – After boiling the potatoes drain them well or any excess liquid can cause the mashed potatoes to break down.
• Buttermilk – If you prefer, heavy cream or half and half or sour cream can be used in in place of buttermilk.
• Homemade Buttermilk – You can also make your own buttermilk. To each one cup of whole milk add 1 tablespoon of fresh lemon juice or white distilled vinegar. Let stand for 5 minutes, then stir and proceed with the recipe.
