expired Gold Medal Pork Krackles 50g $1.50 (Regularly $2.15) @ Woolworths
These seemed popular with some of the OzBargain keto crowd last time and they rarely go on sale.
I tried some last sale and they are pretty tasty but the ingredients aren't suitable for those that prefer "clean keto", and definitely not suitable for carnivores.
Pork Rind, Vegetable Oil, Salt, Hydrolysed Soy Protein, Tapioca Starch, Yeast Extract, Flavour Enhancer (621), Anticaking Agent (504, 551, 341), Food Acid (262), Colour (150c), Herbs And Spices, Vegetable Powder, Flavour.
Edit- it's probably worth mentioning that these are $30.00/kg. I make home-made rinds with pig skin from Coles for ~$6.00/kg, it's usually less than that though as I try to only buy the skin when it's on clearance the day before "best before".
