Crunchy Cheddar Cheese. Where Can I Get It?

Hi LD'ers. Back in the day, I used to buy the Seriously Strong brand of extra mature cheddar and there were crunchy crystals in it. Unfortunately, as the brand got popular, their cheeses got poorer and poorer and now it tastes like a generic run of the mill one.

I have come across a couple of similar 'crunchy' cheddar in the past, but that was a while ago and none seem available now

Recently, I was suckered in to buying an extra mature 'crunch' cheddar at an extortionate price from Morrisons, but it was just like a normal Pilgrims Choice one.

Does anyone know where I could buy some crunchy cheese, if you know what I'm talking about?
