Peanut Butter
On a recent trip we decided to have some biscuits and peanut butter for lunch; but taking peanut butter can be a bulky if you take a jar, messy if you decant it into something else, and potentially very messy if it leaks !
A while back I bought a small vacuum seal machine, so I :
cut some bags into triangular shapes,
folded down the tops (to keep the top of the bags clean so they can be sealed),,
filled them with peanut butter, then
vacuum sealed them shut.
To eat, I cut open the end and squeezed the peanut butter out. Easy to carry, no mess !
