Aibu to find it annoying and childish when people don’t share recipes. As if it makes them special to be the only one who can make a dish.
Even giving a general direction is fair enough e.g. the chicken has paprika and cumin or ‘I put beetroot in the chocolate cake but it’s a family secret recipe so I won’t go into detail’ is fine.
My mil once told me the recipe for dh’s favourite stew she made ‘is somewhere on the internet maybe’ eyeroll.
At least own it and say ‘I want to be the only one able to make his favourite dish’.
It’s more weird when vague acquaintances won’t share. E.g. church bring and share, but won’t share the recipe.
If I make the cake at the next bring and share we will all know it’s Gladys’ recipe. If I make it at the school cake sale how will that affect Gladys?
