I use to buy the regular packet bread crumbs from the supermarket, (this was MANY years ago), but since they added the dreaded preservative 282 into most bread/wheat products I stopped purchasing it. I dare you to go read the fact sheet.
This is one of many chemicals I stay clear of in the cooking sector.
When I make Tupperware Jel Ring sandwiches or a Jel Ring Tuna Mornay Bake, I place the crusts into freezer bags. When, I have several bags stored in the freezer (and it is getting too cluttered), I pour them onto a baking tray; put them in a 200C oven and bake for about 10-15 minutes.
Afterwards, I put them through the blender and then into a plastic container ready for the freezer again. I keep the bread crumbs in the freezer and use when needed. They can last up to 6 months (but this never happens as I use them regularly in my cooking).
Do you also have a problem with broken SAO’s or ALDI Sanz crackers?
Don’t throw them out! Blend these also and add to the home-made frozen bread crumb mix.
