I actually use some ancient(but really clean, honest !) chickpeas and keep them separate from the other beans and pulses in case I ever get the urge to cook them lol...
Jugglering that is exactly what I do with the chick peas that i found at the back of my cupboard and must have been so old I'm surprised they didn't sprout! Anyway I keep them in a container with the piece of parchment that I place them on and use them time and time again. No need to buy these baking beans.
I bought a packet of macaroni to use in my pastry cases. Any pasta or chickpeas or dried peas will do. (Line pastry with greaseproof paper and then fill with pasta.) It has been used loads of times and is now a lovely nutty brown. You only something to stop the base of the case rising up during cooking. Remove paper and pasta and return case to the oven for another 5 -10 minutes (depending on whether you will need to cook further with filling or not)
