Split Pea Soup - PUBLISHED

http://www.vintagerecipes.net/books/twentyfive_cent_dinners/oatmeal_and_peas.php

1 - This is surprisingly good! The oatmeal makes lends and unctuous texture that is quite pleasing. I could try it, next time, with some Frenchifying flavours like bay and/or thyme, maybe some carrot? I thought of adding stock instead of just water, but frankly, I don't think it needs it.

4 oz of fat pork or bacon (about 4 slices of thick bacon)
2 onions, chopped
2 tsps of salt
1 tsp of sugar
1/2 tsp of pepper (maybe more?)
8-12 cups cold water
2 cups of yellow split peas
4 oz of oatmeal

1. Cut the pork into lardons along with the onion and render the fat at medium heat for about ten minutes.
2. Season with the salt, sugar, and pepper, then add the cold water and the peas. Bring to a boil and then simmer until the peas become quite soft.
3. Stir in the oatmeal and simmer for another twenty minutes.
