I'll agree to agree with Megan on the Marmite. Especially Marmite XO, which is the nectar of the gods.
I've got a device in my kitchen drawer which I no longer need to use: it's a jar & bottle opening tool that makes it much easier to open those pesky lids. There are many models on the market & you can buy them pretty much anywhere. Amazon has a large selection, for example.
My mother bought one back in the 1980s & it was so useful that I bought one myself when I moved out. She called hers 'The Husband'.
