I had Scotch eggs on Easter a few years ago at my brothers apartment. They were delicious. I’m not a fan of sage, so I usually use a sausage with sage that doesn’t overwhelm. They were delicious. I haven’t tried making them myself yet, but I intend to.
I use Jimmy Dean sausage. It’s the best brand you can get. Usually I get it on sale for $3 per pound.
A one pound tube of JD’s makes 4 eggs. It’s hard to eat 2 without feeling full and they stick to your ribs. It’s not really a lot, just a sausage and eggs breakfast, but for some reason I feel more than sated after just a pair.
