What is the difference between white and brown miso?
Length of fermentation, largely. Sweet white is short-fermented, mild and slightly sweet. Brown rice and barley misos are darker, saltier and stronger.
Should I boil miso?
No. Stir it in off the heat or well below a boil. Boiling flattens the flavour, and with unpasteurised paste it defeats the object.
Is miso gluten free?
Some are and some are not – barley miso is not. Check the individual pack, as the grain used varies by product.
How long does an open jar keep?
Months in the fridge. It is a fermented, salty product and keeps well; the colour may darken over time, which is normal.
