Ripe pear and Roquefort on bitter leaves with toasted walnuts and a walnut oil vinaigrette. The pear is soft and sweet, the cheese is sharp and salty, the walnuts add crunch and a slight bitterness that ties it all together!
Put the walnuts in a dry frying pan over medium heat. Toast for 3 to 4 minutes, shaking regularly, until golden and nutty-smelling. Watch closely, they burn fast. Tip onto a plate to cool, then break up roughly by hand.
2. Make the vinaigrette
Whisk the Dijon and red wine vinegar together in a small bowl. Add the walnut oil and olive oil in a slow stream, whisking, until smooth and emulsified. Season well with salt and pepper. It should be sharp and nutty with a bit of backbone.
3. Prepare the pear
Core the pears and slice thinly, about 5mm (no need to peel). Toss briefly in a little lemon juice to stop them browning, just a light coating.
4. Assemble
Dress the leaves lightly with about two-thirds of the vinaigrette and toss gently. Divide between plates or arrange in a bowl. Lay the pear over the top, scatter the Roquefort in rough chunks, and finish with the walnuts. Drizzle over the remaining vinaigrette just before serving.
5. Serve immediately
This salad doesn't sit well once dressed, so bring it to the table straight away, before the leaves wilt and the pear softens. Five minutes is fine, thirty is not.
Notes
Roquefort is traditional, but Fourme d'Ambert (milder) or Bleu d'Auvergne (less intense, still AOP) work well too.
Walnut oil is for the real French flavour. It goes rancid quickly, so keep it in the fridge.
The leaves: mâche, frisée and radicchio are classic. A "bistro salad" or "bitter leaves" bag does the job.
Add vegetarian lardons if you fancy, pan-fried crisp and scattered over while warm. A common French variation, and a good one.
