Food is supposed to taste good and food is made fresh(ish) everytime you make it - you're never going to eat a feast served by Emperor Nero because his cooks are dead and cooking is a very artistic job - even a contemporary of theirs wouldn't cook a precisely identical feast. Make food how you want to eat it and enjoy.
Broaden your culinary horizons by tasting meals based on historic recipes if you want, have someone's home cooked dinner where they use a mix of ingredients and spices that they like or try and replicate something you ate at a restaurant but tweak it to be more to your liking.
Food is an extremely ephemeral thing that we consume everyday because we need to love - we can enjoy this daily task by making it to our own tastes without fearing judgement from others.
