>>2529759One thing I've realised lately is that jalapeno cheddar (or any cheddar with things added like blueberries etc.) will last a LONG time while /out/. Just as long as it's not a hot day.
The vegetable matter obviously remains moist and that stops the cheese from drying out. I have had a decent-sized block with me for 4 days before and it not only stayed edible but actually very enjoyable.
