Make IKEA's iconic meatballs at home

I had a friend who was so obsessed with Ikea's Swedish meatballs that he bought them frozen, in bulk, from the IKEA Food Market, and kept a bomb shelter ration's worth in his garage freezer. And this was years before anyone heard of Covid-19, or thought to hoard hand sanitizer or toilet paper.

My friend has since passed on (his death was not meatball-related), but it would have given him great peace of mind to know that IKEA has released its closely-guarded meatball recipe (including their singular cream sauce, which may, in fact, have had something to do with my friend's death) so that anyone can reproduce the IKEA cafeteria experience in the privacy of their own home.
