Asda is also offering the larger 750g tubs for considerably less than Sainsbury's and Morrisons's non-sale price.

I tried supermarket cafe breakfasts from Morrisons, Tesco, Asda and more - there's two I never want to eat again Therefore Lidl shoppers are getting 100g extra for 10p less than Tesco customers are on Lurpak tubs right now.

I was left most disappointed by Lidl, Co-op and Asda - and won't be rushing to buy their butter again. However, Tesco gave another good alternative with their Butterpak which I wouldn't hesitate buying again.

Olivia Potts, author of Butter: A Celebration, extols the virtue of cultured butter (made from cream that has been allowed to ferment) in dishes that showcase its tangy flavour – for example, her butter and vanilla shortbread, stirred through polenta or melted onto steamed vegetables. “Butter from Brittany is heavily seasoned with salt in a way that makes it taste even more buttery,” she adds, “so it’s particularly good in Breton bakes that are supposed to taste distinctively of butter, such as Sablés Breton [butter biscuits].”It spread so easily, was creamy and tasty. It melted straight into the toast and all four of us agreed it was the best out of the lot.
