We made this a couple of weeks ago and liked it so well we gave it another go yesterday. We had it for lunch and again for dinner. Instead of bacon we used a smoked hock that we boiled for a while in broth before putting the soup together. The leeks sweated down in butter in another pot before adding the potatoes and the broth. I kept the hock out to cool. After the soup was cooked and blended the diced meat from the hock was added back.
