I have a question about the ingredient "pancetta rashers, sliced into ribbons" on the recipe "Terence Hill's Beans" from Marie Viljoen.
Ooops! Looks like your question didn't make it - feel free to ask it in the comments!
Rashers is the British word for slices . . . so I would take slices of pancetta (may have to unroll them) and cut into long julienne to make ribbons.
I agree with usuba dashi's comment and advice on technique. These days you can buy a whole rolled up hunk of pancetta or a thick slice as opposed to just those packets of ultra thin things.
