You should not be listing “ingrdients” in posts unless you have something to actually say. You already list the ingredients in the recipe card. When talking about ingredients, you should be using a H2 that says “Recipe Ingredients” in the post, then providing two things; a labeled photo of the ingredients, then talk briefly about the main ingredients. That’s how you show your expertise. I’m confused why you would be using H3s at all. You certainly don’t need to.
