This poster was talking about these meatballs at Ikea..they were so good the last time I had them there...I feel like shopping.

2 lbs ground meat (turkey, beef, chicken)
2 Tsp garlic powder
2 Tsp onion powder
1 Tsp ground cinnamon
1/2 Tsp ground nutmeg (freshly, if you have the means)
dash of salt & pepper
1 egg
1/2 Cup gluten-free bread crumbs (I use the breadcrumbs I make from Gluten-Free Flax Bread)
1 boullion cube (I use Hormel Herb-Ox brand as it is on their gluten-free list)
1/2 cup water
1/2 cup light cream or whole milk
1 cup sour cream
In a large bowl, mix meat, spices, gluten-free bread crumbs and egg together.In a large skillet, preheat with 2 tbs olive oil. Using a small cookie scoop (or tbs measure) make 3/4" meatballs and place around the preheated pan. Cover and allow to cook for about 5 minutes - or until the bottoms are slightly crusted (the tops will be "steamed" from covering the pan). Carefully flip the meatballs around. Cover and cook another 5 to 10 minutes until the meatballs are cooked through.Meanwhile, in a microwave safe bowl heat the boullion cube and water (I crushed up my cube slightly so that it would dissolve). Mix the water/boullion mixture with the cream and sour cream well. Set aside.Uncover meatballs and add the sour cream mixture...making sure to scrape up bits from the pan as you stir it in. Allow it to come to temperature, and cook almost to boiling for about 3 minutes - stirring to coat all the meatballs as you do thi
