We love that! I usually add a few drops of balsamic vinegar and some Italian herbs, such as oregano and basil, maybe some rosemary. I love the idea of letting the olive oil sit for a few hours to let the flavors meld.
I cannot use Italian seasonings, they do not list all ingredients and Rosemary makes my throat seize, like a charlie horse does calf muscle. Oregano causes a headache as does sage, a little seems sufficient but some cooks are heavy handed and then I am ill after dinner, not digestion, am dizzy and headache.
I have known people who will put aside a dish from recipe for a person who is allergic to pineapple (ER breathing blockage) but won't change a seasoning for someone else's food reaction consequences. If they can breathe and don't get hives, It is all in your head. Yes, headache, I can avoid knowing what is in my food. So, looking for ideas. I love balsamic vinegar. Have not purchased for a long time, I like the reminders, from good posts of what I used to use.
