I bought one of those George Foreman grill things the other day, as son had to cook something for beavers and it was nice and portable for him to cook his chicken satay skewers on.
I cooked 8 sausages on it and being the skank I am, I forgot to empty out the fat collector. When I remembered I found the pot full to the brim with solidfied fat. I've just cooked 4 homemade burgers on it, which were just beef mince and seasoning, and again, it's filled the pot.
I feel pleased to think we would have eaten all that if I'd fried as usual, but I'm also weirdly fascinated to see it in a big disgusting lump. There's probably half a pack of lard there just from 2 meals.
