I really need a quick easy meal option tonight (coming to the end of a 3 day migraine!) so got a jar of Homepride pasta bake. When I opened it there is a thick paste on the inside lid and top of jar but the rest is a normal sauce consistency. Is this normal for these jars? It is in date until 2022. Sorry if this sounds stupid (again blame the migraine or perhaps I am just stupid 😂 🤦♀️) I would really appreciate advice either way.
