I find that a large chunk of posters on MN have a weirdly proprietary view of what other people enjoy eating. Especially when it comes to sauces or condiments.
I don’t enjoy dry food. Whatever meal I eat will typically have a sauce, gravy or condiment of some kind. If I’m in a fine dining establishment then I’ll pick an item that comes with a sauce - although it will undoubtedly be called a jus, so that makes it alright 😂 If I’m in a greasy spoon and having a fry-up then I’d want either ketchup or brown sauce.
To me, it’s both a texture and a taste thing. I enjoy the flavour of the food and sauce together. And I enjoy the texture more too.
Dishes that are already saucy such as lasagne, curry etc don’t require any additional sauce (for me).
I don’t ever add salt to a meal without tasting it first (in fact I almost never add salt to my dinner, only occasionally on chips!) It’s just I like a side helping of sauce with any dry meal which might be anything from sour cream to ketchup or gravy, or a specialty sauce.
Once upon a time I knew a (very posh) woman who carried a bottle of vinegar around in her handbag. She couldn’t enjoy a plate of food without a liberal sprinkling of vinegar -even on curries. Honestly the most unusual thing I’ve ever seen, but it never, ever crossed my mind to think she was being rude or to sneer at her. I found it genuinely hilarious as it was so unusual and we used to laugh about it when she whipped her bottle out.
It’s not “rude” to add condiments to the food to please your palate FFS.
I couldn’t give a shit how they’re “supposed” to be eaten. If I enjoy the taste more by adding sauce or condiments what’s wrong with that?! Am I only allowed to eat food the way that other people say it should taste?? Daft talk.
Im neurodivergent too - in OP’s shoes I would either explain I struggle with the smell so deliberately arrange the seating so I’m well away from her plate, or just pick a different type of venue as a PP suggested, like afternoon tea.
If you really can’t bear the smell OP, then you can’t 🤷♀️ That’s fine, but to think your preferences are more important than hers is a tad entitled. You can’t police other people’s plates. Imagine if you were told you had to change the way you enjoyed eating your dinner - you’d be understandably quite miffed!
You haven’t said what you do if the next table in the restaurant order something with heavy tomato sauce, or a BBQ sauce - how do you cope with that smell then?? It’s not just your MIL that adds these condiments….
Only being allowed to put sauces on certain types of food or else be considered rude is one of these confusing social rules that I’ll never, ever understand. It makes no sense at all. We all have different palates so why would we all like the same tastes/textures?! If that was the case we’d all be ordering the same dishes, cooked in exactly the same way - which obviously isn’t the case. Theres nothing wrong with choosing to customise your plate of food so that it gives you the greatest pleasure.
Hope you figure out a solution OP that keeps everyone happy.
