Fermented Tomato Sauce (Ketchup)

Nikki Di Costa (health and lifestyle coach, blogger, business diva and mummy) gave me permission to share this amazing recipe with you. If you have my book, Keeping it Simple, you will know that I use whey in the Teriyaki sauce recipe. Whey has amazing preservative properties. Yes Whey! This is a delicious, rich and good for you alternative to traditional ketchup. When the kids want to add this to everything but ice cream, you can feel comfortable saying yes!

Once made it will keep for ages in the fridge, then serve it with any or all of the following:

Spicy Skinless Sausages

Easy Sausage Scrolls

Traditional Aussie Meat Pies

Vegetarian Sausage Rolls

Cheeseburger Sausage Rolls

Beef and Ale Pie

Oven Fries and Lime Aioli.

Chicken Parmigiana

Air Fryer Chips

Decant into a bottle and add a little more whey onto the top of the sauce. Allow to sit at room temperature for 2-3 days.


Stir in the whey and refrigerate. This will keep for 3 months in the fridge and is completely delicious on everything, except ice cream, naturally.
