How to stop sil family being mean to Mil

[Kannet]

My MIl is a lovely lady, but very quiet and has simple tastes and does believe in quantity over quality.

Anyway a few years ago BIl and SIL invited her to Christmas dinner alongside SIL family. They all brought a course for a meal and mil was allocated dessert. She decided to go to Iceland and get loads of cheap frozen cheese cakes and vienettas. This wasn't about saving money it's just what she likes and assumed everyone else would.

SIL has mentioned that her family joke about it all the time. They thought she should have brought some fancy desserts and it's become a family joke

They have invited her again this year and again she has been allocated dessert and she plans to do the same thing. I can just imagine SIL rather nasty family nudging and laughing. I have tried to gently encourage to bring something different, but she keeps saying "it went down so well last time". I can't tell her that they where joking about her. She would be devastated. I really don't know what to do.

Well done you, to have thought of such a good solution!

I would have told SIL she is a bitch myself, but your way is more diplomatic!

She sounds lovely and your SIL and her family sound like rude fuckers.

Rather than do an elaborate ruse with other desserts, why isn't your DH telling SIL to stop being such a bitch to MIL?

Viennetta with Baileys poured over it is the food of Gods. I would take a bottle and hey presto - instant posh dessert - no ones going to be laughing then - they'll be asking for more.

They asked her again.

I would definitely take that as a vote of confidence in her choice, esp if DMum thinks it went down well because it all vanished.

Has SIL got form for being a shit-stirring bitch? Because if not, then it could be a good humoured (and complimentary) joke about how they all fell on it like locusts.

Why do you assume the worst about her family? Or that Vienetta isn't a fab puddding?

You can send your lovely MIL over to me with her desserts. I love Iceland desserts just as much as I love M&S,Waitrose or homemade 'posh' desserts! SIL sounds like a snobby bitch. I would invite MIL over to yours instead!

PIL brought two £1 cheesecakes from Morrisons to our xmas meal last year, to feed six adults and four teenage boys. They're very comfortably off but somewhat tight. Everything on the cheap.It pissed me off tbh. I'll be making a similar effort to their hosting this year.

Well done for sorting this OP. Your SIL family sound like horrible bullies. They clearly wanted another chance to have a smirk and exchange knowing glances. Pricks.

Gosh, as a super baker here (even if I say so myself) I really like a Viennetta. I would happily, greedily, double help myself to a Mint one.

A great solution this year... your SIL is still a rude bitch coming from an awful family.
