Other Plant Milks for Cooking: When to Use (or Avoid) Them

Coconut Milk 🥥

Best for: Thai curries, Indian dishes, Southeast Asian soups

Why: Authentic flavor for Asian cuisine, very creamy, heat stable

Avoid for: Mashed potatoes, Italian pasta, anything where coconut flavor would be weird

Note: Use canned "coconut milk" for cooking, not the carton "coconut milk beverage" which is too thin.

Almond Milk 🌰

Best for: Lightening up soups, recipes where milk is just for moisture

Why: Very neutral, won't add calories or change flavor much

Avoid for: Creamy dishes - it's too thin and watery. Will make sad mashed potatoes.

Rice Milk 🍚

Best for: People with nut and soy allergies

Why: Hypoallergenic, neutral flavor, affordable

Avoid for: Anything creamy - it's the thinnest plant milk. Better as a last resort than a first choice.

Hemp Milk 🌿

Best for: Honestly? Not much for cooking.

Why to avoid: Strong, grassy flavor that overpowers most savory dishes. Save it for smoothies.

Substitution Guide: Replacing Dairy in Recipes

Replacing Regular Milk (1:1 ratio)

1 cup dairy milk = 1 cup plant milk

Use: Oat milk or soy milk (unsweetened)

Replacing Heavy Cream

1 cup heavy cream = 1 cup cashew milk OR ¾ cup oat milk + ¼ cup plant-based butter

For extra richness, use full-fat coconut milk from a can

Replacing Half-and-Half

1 cup half-and-half = ½ cup oat milk + ½ cup cashew milk

Or use oat milk "barista blend" straight (it's thicker)

Replacing Buttermilk

1 cup buttermilk = 1 cup plant milk + 1 tablespoon lemon juice or vinegar

Let it sit for 5 minutes to curdle. Works with any plant milk. Also useful for baking.

Cooking Tips: Getting Perfect Results Every Time

1. Always Use Unsweetened for Savory Dishes

This is rule #1. Sweetened plant milk in mashed potatoes or pasta sauce tastes bizarre. Check the label - you want 0g sugar (or close to it).

2. Don't Boil Plant Milk Directly

Gentle heat is your friend. Add plant milk to hot dishes after removing from high heat, or simmer on low. Boiling can cause separation or curdling (especially with soy milk in acidic sauces).

3. Add Plant Milk Gradually to Hot Dishes

When making gravy or sauce, add plant milk slowly while whisking constantly. This prevents lumps and temperature shock that can cause curdling.

4. Thicken Sauces Before Adding Plant Milk

For gravies and sauces, make your roux (flour + fat) first, then gradually whisk in plant milk. The starch helps stabilize the milk and prevents separation.

5. Use Full-Fat Versions When Possible

Light or low-fat plant milks are too thin for most cooking. Look for "original," "full-fat," or "barista" versions for the best texture.

6. Season Generously

Plant milks are slightly less flavorful than dairy. Be generous with salt, pepper, garlic, herbs, and other seasonings to compensate.

7. Let Plant Milk Come to Room Temperature

Cold plant milk can cause fats to seize or create uneven texture. Take it out of the fridge 15-20 minutes before cooking.

Troubleshooting Common Cooking Problems

Problem: Plant milk curdled in my sauce

Solution: You likely added it to something too hot or too acidic (like tomato sauce). Next time: (1) Remove from heat before adding milk, (2) Temper the milk by slowly adding hot liquid to it first, or (3) Use oat milk which is more stable than soy.

Problem: My mashed potatoes are watery

Solution: You used a thin plant milk (like almond). Switch to oat milk or cashew milk. Also, heat the plant milk before adding to potatoes, and use less than you think you need.

Problem: Gravy is lumpy

Solution: Add plant milk more gradually while whisking constantly. If lumps form, blend with an immersion blender or push through a fine-mesh strainer.

Problem: Sauce is too thin

Solution: Either use a thicker plant milk (cashew or barista oat), or add a cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons cold water) and simmer until thickened.

Problem: Soup tastes "off" or too sweet

Solution: You probably used sweetened plant milk. Always check labels. Fix it by adding more salt, acid (lemon juice), or savory seasonings to balance the sweetness.

Recipe Ideas: What to Make with Plant Milk

Ultra-Creamy Mashed Potatoes

Use oat milk + vegan butter. Heat the oat milk before adding. Mash until smooth and season generously. Secret: add roasted garlic for extra flavor.

Perfect Mac & Cheese Sauce

Make a roux with vegan butter and flour, gradually whisk in oat milk, add nutritional yeast and your favorite vegan cheese. Creamier than dairy mac & cheese!

Restaurant-Quality Alfredo

Use cashew milk for ultimate creaminess. Sauté garlic in olive oil, add cashew milk and vegan parmesan, season with salt, pepper, and nutmeg. Toss with pasta.

Creamy Tomato Soup

Roast tomatoes with garlic and onion, blend until smooth, add oat milk for creaminess. The oat milk balances the acidity beautifully.

Smooth Country Gravy

Make a blonde roux, gradually whisk in soy milk, season with sage, thyme, salt, and plenty of black pepper. Perfect over biscuits.
