Ingredients

1 cup instant nonfat dry milk powder
1/4 cup cornstarch
1/8 cup dried onion flakes
2 teaspoons garlic powder
1/2 teaspoon salt
1/2 teaspoon white pepper
2 cups parmesan cheese dehydrated
2 tablespoons sour cream powder

Instructions

Mix all the ingredients thoroughly in a bowl. Store in an airtight container in a cool, dry place.
When ready to cook, measure out 1/4 cup mix and add it to a saucepan over medium heat. Stir in 2 tablespoons melted butter and 1 cup milk or water depending on your preference or dietary needs. Whisk continuously. Bring the mixture to a gentle boil, continuing to stir constantly to avoid scorching. Cook until the mixture thickens to your desired consistency, then remove from heat and use as needed.

Notes

To improve shelf life: Use fully dehydrated, low-fat parmesan powder, not shredded or oily cheese

Choose commercial sour cream powder (not DIY blends)

These are formulated to be shelf-stable 12–18 months when stored correctly.

Add an Anti-Caking + Moisture Buffer (Quiet Hero)

You already have cornstarch — good. Let’s help it a bit.

Add ONE of these

¼ teaspoon additional cornstarch

or ¼ teaspoon rice flour

This helps absorb humidity and keeps powders from clumping.

Reduce Oxygen Exposure (Huge for Dairy). Oxygen = rancid flavors over time.

Best practices: Store in airtight glass jars (mason jars > plastic)

Fill jars as full as possible (less air space)

For long-term storage:

Add a food-safe oxygen absorber (100cc)
