My first totally successful chicken, bacon & mushroom pie. After his first mouthful, my son said 'This is delicious, Daddy'. (He will always wolf down my concoctions, and has correctly identified me as an immeasurably better cook than my ex-wife, but I think this was his first actual compliment.)
I usually get the cheapest white wine I can find to cook with, but last time it was so weak I had to use the whole bottle, and the pie ended up tasting like vinegar. So this time I bought a semi-decent bottle. Also, my lardons usually disintegrate, but this time I fried them in advance and only added them to the mix just before putting it in the dish.
A tip: never cook with any wine you wouldn't be happy to drink.
