Simmered how? In water? That is a lot of garlic and onion....
Mainly, the water/liquid released by the onions (and later, the pork).
It took a few hours, but it got there. I also had some sticking in the pot, so I had to do a few rounds of boiling water and baking soda to get that up. Once it had reduced, I put it all in a smaller pot to simmer in the oven...and it simmered over and got all over everything in the oven, so now that's going through its four-hour cleaning cycle.
I was pretty irritated, TBH, partly due to that and partly because of my doctor visit earlier yesterday, but when it was all done, I had MrsT taste it (this is her home-cooked birthday meal - somehow, she gets three: home-cooked, local restaurant, and fancy restaurant
), and for all that work, I thought, "This stuff better be good!"
She tasted it and flipped her lid, and it should be even better today, because it's sat overnight.
You'll see it posted later today.
