How To Make White Pizza Sauce with Sourdough Starter
This white pizza sauce recipe has been based on my recipe for sourdough béchamel sauce, which is great for using in lasagne. It uses a very similar technique. To ensure this sauce works, I recommend having all the ingredients on hand before you start. You don't want to leave this sauce unattended.
In a medium sized saucepan, melt the butter gently over a low heat. You don't want to brown the butter, so just allow it to gently liquefy.
Now, add the sourdough starter (or sourdough starter discard) and around 50g of milk (a good splash) and gently loosen the sourdough starter with a whisk so that the butter, sourdough starter and milk form a loose paste (this is like a roux but with a slightly different technique because you're using sourdough starter instead of flour). Don't worry if it's a lumpy mess, it will all come together. If you're having trouble with the paste, take it off the heat so the sourdough starter doesn't cook before it's dissolved.
Now, add the milk in small batches while continuing to whisk the white pizza sauce. You can do this over a low heat.
Once all the milk has been added and the sauce is starting to thicken, add the minced garlic, crumbled sharp cheddar, salt, pepper and onion powder.
Continue to whisk until the cheese is completely melted and the sauce is thick and smooth. I usually increase the heat to medium for this to ensure the milk is heating adequately.
Once the sauce is thickened to your liking, remove from the heat and transfer to a container or bowl. Allow to cool before adding to your pizza base.
If you like a super smooth sauce, you could use a stick mixer to smooth it out or add it to a food processor. I don't do this because I find that it's fine once it's on a pizza and there's cheese melted on top.
Tips for Making The Best White Pizza Sauce with Sourdough Starter
This sauce is really easy to make, but there are a few things you can do to ensure you have success with it each and every time you make it.
- Ensure your sourdough discard is at room temperature before adding it to the melted butter. This will ensure that it mixes into the butter more easily. Cold starter tends to be stiff and harder to dissolve.
- You want a crumbly cheese that will melt well to make this sauce. A sharp aged cheddar cheese or parmesan cheese both worth really well. You can add a little of each if you like too.
- Whisk the sauce continuously while cooking to avoid lumps and ensure a smooth consistency. This also helps the sauce thicken gradually.
- Allow the sauce to simmer gently over low to medium heat. This slow cooking process allows the flavors to meld and results in a rich, cohesive sauce.
- Be cautious not to bring the sauce to a boil, as this can cause it to separate. Keep the heat low and simmer until the sauce thickens to your desired consistency.
- I've used black pepper, but you can use white pepper if you prefer. This will keep your white sauce lighter than using black pepper.
What Pizza Toppings Pair Well with White Pizza Sauce?
