I love these bread rolls (panecillos in Spanish), they are by far the best gluten free "bread with crust" that I have tasted, even better than Sainsbury's freefrom baguette.
Unfortunately I have not seen this brand in the UK, I bought this packet when I was in Spain over Christmas.
How can I describe it? The middle is soooo soft and fluffy, and the crust is crusty but not too much. It reminds me of those French breads made with milk in the dough, just a tiny bit sweet and very moorish.
Doing a bit of online research it seems that this brand is Dr Schar line of products for the Spanish and Portuguese markets, so definitely not available in the UK.
