I have been sick... for a while. This is a soup my grandma used to make for me. We always called it Irish stew, but it's really a very simple, five ingredient, soup. I haven't had this dish in years. Start out with about 4-6 medium potatoes and a medium yellow onion. Peel and chop the potatoes. They don't need to be perfectly cubed or diced. Grandma kept them coarsely chopped - kinda rectangular pieces. Dice the onion fairly finely - no big chunks.
Add them all to a large pan and add water and salt. The water should cover the ingredients with at least an inch of water. Start with a modest amount of salt to keep things evenly seasoned. Boil until the potatoes are fully cooked and tender.
Before serving, be sure to adjust the salt to your preference. Grandma used to add evaporated milk when serving the soup. But, that would turn my insides into outsides, so, I use almond milk.
She would serve it with her homemade bread. This is the type of food I grew up eating; simple, ungarnished, unadorned, comforting food.
