This homemade ketchup is so easy to make from scratch in a slow cooker. It does come close to those name brands in terms of taste, texture, and color. I've never had a tomato paste-based ketchup that I liked so I decided to cook down crushed tomatoes instead.
2 (28 ounce) cans crushed tomatoes
½ cup water, divided
⅔ cup white sugar
¾ cup distilled white vinegar
1 teaspoon onion powder
½ teaspoon garlic powder
1 ¾ teaspoons salt
⅛ teaspoon celery salt
⅛ teaspoon mustard powder
¼ teaspoon finely ground black pepper
¼ teaspoon cayenne pepper, or to taste
1 whole clove
Transfer strained ketchup to a bowl. Cool completely.
Taste and adjust salt, black pepper, and cayenne pepper as desired.
