First make the garlic croutons: just place the cubes of bread in a bowl together with the oil and the garlic, and stir them around so that they get an even coating.
Then arrange them on a baking sheet. Bake them on a high shelf in the oven for 10 minutes or until they are crisp and golden. One word of warning: do use a kitchen timer for this operation because it's actually very hard to bake something for just 10 minutes without forgetting all about it. I have baked more batches of charcoal-coloured croutons than I care to remember! Then allow them to cool and leave them on one side until the salad is ready.
Then prepare the dressing – cut the cheese in half and use a small, sharp knife to peel it carefully like a potato, paring away the skin from the soft cheese. Place the cheese in a small saucepan. Next measure in the crème fraîche, but don't heat it until just before you are going to serve the salad. When you're ready, mix the salad leaves together, breaking up the larger ones into manageable pieces, and arrange the salad on the serving plates. Slice the apple, leaving the skin on, and put the slices in a small bowl, then sprinkle on a little cider – just enough to give the slices a covering.
After that, pat them dry and arrange over the salad leaves. Now place the saucepan over a gentle heat and blend the cheese and crème fraîche together, for about 3-4 minutes – using a small balloon whisk – until the mixture is smooth. If the cheese is very ripe and runny, you may not need the dry cider, but if the centre is less ripe, you will need to add a little cider to keep the mixture smooth. The main thing is to melt the cheese just sufficiently for it to run off the whisk in ribbons, while still retaining its texture. Don't allow the cheese to overheat or it may go stringy – it needs to be melted rather than cooked.
Next, using a small ladle, pour the dressing equally over the salad and finish with a scattering of croutons. Alternatively, you can hand the dressing round the table and let everyone help themselves.
