I would have to say the cream of soup mix recipe that I found on this website. I tweaked it a bit so I could eat it. The recipe calls for powdered bouillon granules, I can't eat this because they all contain MSG. Instead I use celery salt, along with the other spices and a pinch of salt. Then after it's fixed up I add a gel bouillon I found that I can eat. This is my tweaked recipe
2 c. instant milk 3/4 c. cornstarch 1 tsp. onion powder 1/2 tsp. thyme 1/2 tsp. basil 1/4 tsp. pepper
Mix well and store in an airtight container. (I usually make at least double because I use this so much.)
Add 2/3 c. of mix to 2 c. of water in large microwavable bowl. Stir
well with whisk. Microwave on high 3 minutes, stir again with whisk.
Microwave an additional 2-3 minutes until thick. Use in place of canned soup in a recipe. You can add whatever veggies or meat for a cream of soup. If I'm making chicken or beef flavored I'll add the gel bouillon after the microwaveing.
