My daughter is a PB fiend and seems to get through about a jar a week. I know that's it's not the healthiest thing but she's veggie so I figured it's good for the protein boost. I've been buying the Aldi ones lately (have just noticed that their more expensive one - still only 1.25 - is just peanuts; no added palm oil, sugar or salt). Any other suggestions, Mumsnetters?
Consider making your own if you have a decent processor? I make my own almond butter and would never buy it anymore, it's so much better! Buy bags of peanuts, roast in oven for 15 mins if you want, add a bit of salt or other flavorings and chuck in the processor. It takes a while to turn into butter but so worth it!
