did you say that you used to make it all the time? if you did, your mum made it this time, it's going to taste slighly different cuz she will have her own touchto it. i dont think you have anything to worry about. and if you haven't eaten a certain food for a while they can taste different because your taste buds do change with time.
so, you might be losing your sense of taste but not your lunch
