So you are probably wondering why in the world would you want to make Homemade Ketchup in your Slow Cooker.

Well for one it’s much cheaper than buying a bottle at the grocery store. A non-organic bottle of Heinz ketchup runs anywhere from $3.50 to $4.00 here locally.

Making your own Homemade Ketchup using this recipe, I estimate you can make an equivalent amount for half the price. Your mileage may vary depending on the cost of ingredients in your area.

Regardless of any cost savings, I personally enjoy making my own condiments and sauce. They just seem to taste better when I make my own.

Some of you are probably thinking it’s not worth the effort just to save a couple of bucks. Well that might be true for some but I know many of you enjoy making your own condiments and sauces.

Plus you can easily tweak the recipe to your liking. For example, if you want your ketchup to have a little kick to it, you can add some sriracha to the mixture. The possibilities are endless.

If you don’t have any Apple Cider Vinegar on hand, you can try one of these substitutes: Rice Wine Vinegar, White Wine Vinegar or just plain White Distilled Vinegar.

Keep in mind that it will slightly alter the taste of the ketchup. But I always recommend keeping a bottle of Apple Cider Vinegar on hand as it’s one of the most used kinds of vinegar in cooking.

Now keep in mind that this homemade ketchup will not taste like Heinz Ketchup. Which in my opinion the best ketchup out there. While this ketchup recipe still has great flavor, this is not a Heinz Ketchup Copycat recipe.

The consistency is a little thicker than what you would get in a bottle from your local grocery store.

Let the sauce sit for at least 1 hour in the refrigerator. This will allow all the flavors to meld. You can use it immediately, but the longer you let it sit in the refrigerator, the more flavorful it will be.
