Chef's pro tip
To prevent lumps when using xanthan gum, you must whisk it with a small amount of cold water or oil before adding it to the sauce. This helps it dissolve evenly and thicken the sauce without clumping.

You actually make it appear really easy together with your presentation however I find this topic to be really one thing that I believe I might never understand.
It sort of feels too complex and very wide for me. I'm looking ahead for your next publish, I'll attempt to get
the hang of it!

I was disappointed after I made this recipe. It had a weird after taste which was probably the Xanthum gum. I’m not a fan of Xanthum gum. I wish there was another low carb way to thicken the sauce. I might try making this recipe again without the Xanthum Gum.

Hi Heidi,
Thank you for sharing your feedback! We totally get that xanthan gum isn’t for everyone. If you’re looking for an alternative, konjac flour (also called glucomannan) is a great keto-friendly option. It’s super low in carbs and does an excellent job of thickening sauces without any aftertaste—just a little goes a long way!
That said, if you’re okay with a slightly thinner consistency, you can skip the thickener altogether and simmer the sauce over low heat to let it naturally reduce. It’ll still be flavorful, just not as clingy.
Let us know if you give it another try with this tweak—we’d love to hear how it turns out! 😊
