I learned how to make soft boiled egg on toast when I was in high school from my brother-in-law, Bob. I was asked about it in a comment so I'll give instructions here. By the way, Jerry loved it this morning, my first time to fix it for him. I usually have it when he takes one of our kids out for breakfast!
Boil enough water to cover egg. After it begins to boil put egg in. Set timer 4 minutes. Make toast. When timer dings run cold water over the egg to stop the cooking and cool it enough to handle. Strike the egg with the edge of a knife to break it, then scoop out the egg on the toast. Enjoy! Mmmmmm! Thank you, Lord, for good tasting, nourshing food.
