It's not weird. ;)
A lot of the time, sauces are so strong and highly favored,
that they cover all taste the main ingredient would have on its own.
And if you got a nice taste without any "added flavor", just enjoy it, as it is. Easy.
If you want another example:
Potatoes (any kind) taste great just steamed, maybe some salt to taste,
but nothing to rival the sometimes rather faint taste of the vegetable.
Slowly sweat some onions in a pan till sweet, add them, and it's already difficult to still taste the tater.
You can make the same argument for Salad, freshly baked bread,
or a carrot, right out of the ground, super tender and definitely sweet (cause not fully grown^^).
I conclude:
If anything, you're simply more culinary open minded than your family.
Now take on this challenge:
Prep some food (that they generally like, e.g. potatoes) but usually
eat with highly flavored sauces or other dishes.
Make sure they did not eat or drink anything with a strong taste before hand.
Then let them have a taste,
only offering salt and pepper on the table. Maybe they like it. At least a little.^^
And if not, you tried.
Good luck, Calari
