One of my favourite things in the world.
I've tried many many brands and types of peanut butter and many different jams.
My perfect snack:
2 slices of freshly baked (got a bread maker) Granary/ Country grain
Some butter, preferably with some tasty salt crystals imbedded. I like ones like this
Thick, thick layers of peanut buter. This will be approx 65-70% of the topping.
The best I have tasted. So far...
Then, the best accompaniment is blackcurrent jam. This then leads to the answer being be about 30-35%. This one is my present favourite.
Accompanied by a mug of tea.
Sorry, yes I'm English. And I like to share
