Tomato and Macaroni Soup
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
In a pot, melt the butter over medium heat.
Add the chopped onion and sauté until translucent.
Stir in the chopped tomatoes and cook for 5 minutes.
Add water and bring to a boil.
Stir in the macaroni and cook until tender, about 10 minutes.
Season with salt and pepper to taste.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
