hi. i'm inviting the family over for a meal on sat and was thinking of making a lamb tagine in my slowcooker. i normally just get the two steaks which (cubed) is enough for myself and my partner. there will be 7 adults altogether, so was just wondering if it would be cheaper to get it from the butchers rather than asda or tesco? and does anyone have any idea of price difference between butchers and supermarkets? thanks in advance.
