Bacon and sweetcorn chowder

I had a couple of corns-on-the-cob that wanted eating, and not very much else in the house.  And the Swan Whisperer has a cold, and I'm recovering from one and now have a bad cough, which is leaving me very drained.  So this was rather comfort food!

1 ½ corns-on-the-cob (it was going to be 2, but there was a Nasty on one of them, so I had to throw half of it out)
1 small tin sweetcorn
1 onion, chopped
1 clove garlic, crushed
1 packet lardons
4 small potatoes, peeled and cubed
About 300 ml milk and the same of water (I didn't really measure)
Pepper, and a dash of chilli sherry (use any chilli sauce, or even powdered chilli, but not too much)

Cook the corns-on-the-cob however you usually do - I usually use my microwave steamer.  Let them cool a bit.  Put the lardons in a heavy-based pan, and cook gently.  Add the onions, garlic and potatoes, cover, and let them cook in their own steam for a few minutes.  Meanwhile, put the contents of the tin of sweetcorn into a blender and process with a little milk until smooth.  Cut the corn kernels off the cob with a sharp knife, and add these to the saucepan.  Add the creamed sweetcorn and the rest of the milk.  Top up to a nice amount with water.  Season.  Bring to the boil and simmer for about 15-20 minutes until the potatoes are cooked.  I actually did this in two lots, letting it stand for about an hour as I was busy.  This may or may not have improved the flavour!
