I have been surprise to find that the puffballs, normally only available in September are already out and doing really well in July. The combination of warm damp ( well wet) weather has done its stuff and the fungi are popping up all over.
It is best to harvest after a dryish spell as they do absorb a lot of water. Also, do take care that dogs on walkies have not had access to them, I am sure they will not add anything to the flavour.
Once collected cut up with a bread knife into slices and fry in butter with salt, pepper and sliced garlic. If you want a bit of spice add some chilli pepper ( dried or fresh). Cook until the puffball is lighly browned. If the fungi has a lot of water in it you can slice it up and put it in a low oven ( around 40 C) for a few hours to dry out. Once cooked the puffball can be frozen and will keep well.
