Fresh Thyme or Dried
For this recipe we do tend to use fresh thyme as it works wonderfully, however if you do not have any, you can substitute it with ½ teaspoon of dried thyme instead. But, if you can get the fresh thyme I feel like it gives it even more flavor!
If you are worried about wasting the rest of your fresh thyme before you can use it in another recipe, have you ever tried freezing or drying your herbs?
Well, Gardener’s Supply Company gives you great instructions on how to freeze or dry your herbs depending on how you want to use them or which herb you are working with!
