Can I use dried herbs instead of fresh ones in this sauce?

Yes, you can use dried herbs if fresh ones aren’t available. However, keep in mind that dried herbs are often more potent than fresh ones. The usual rule of thumb is to use one-third the amount of dried herbs as you would fresh.

What other dishes can I use this Garlic Herb Sauce with?

This versatile sauce works great with a variety of dishes, not just grilled tuna. I also enjoy it with roasted chicken, pasta, or as a dressing for salad.

I’m not a fan of white wine vinegar. Can I replace it with something else?

Yes, if you don’t like white wine vinegar, you can substitute it with other kinds of vinegar such as apple cider vinegar or red wine vinegar. You can even use lemon juice if you prefer a citrusy touch.

Can I add more garlic if I like it really garlicky?

Absolutely! This recipe is quite flexible. Adjust the ingredients to suit your taste. If you’re a big fan of garlic, feel free to add more.
