The classic tarte au citron is tricky with wine, particularly if it’s home made. And the sharper and more lemony (and delicious) it is, the harder it is to find a good match.
Citrus flavours are difficult to match with wine, as I’ve mentioned before, but a classic lemon tart with its combination of sharpness and sweetness is particularly tricky. The better a tart is the more it will tend to strip the flavour out of any accompanying wine, so much so that it’s almost worth serving a shop-bought one (of which there are some very good examples) if you have a serious dessert wine to show off.
Look up any book or guide to food and wine matching and you’ll find a list of foods that are regarded as anathema to wine. I’ve done it myself but have come to the conclusion recently that the problems are often overstated. It may be true that most wines fall out with such ingredients as artichokes or hot curries but they may be the kind of wines you wouldn’t be inclined to drink with those dishes anyway.
