This elegant ham persillade with mustard potato salad is a modern take on the classic French terrine. Prepared in individual jars, it features tender cubes of baked ham set in a delicate garlic and parsley jelly. The dish is layered with a vibrant, herb-flecked pea mash and a tangy potato salad, offering a wonderful contrast of textures and bright, savoury flavours that are perfect for outdoor dining or a refined starter.

How to make Ham Persillade with Mustard Potato Salad and Mashed Peas
Chop enough parsley leaves to measure 1 tablespoon ; reserve. Chop remaining leaves and stems and simmer with broth and garlic in a small saucepan, covered, 5 minutes.
Meanwhile, sprinkle gelatin over water in a medium bowl and let soften 1 minute. Strain broth through a fine-mesh sieve into bowl with gelatin and stir to dissolve. Season with salt and pepper. Set bowl in an ice bath and cool to room temperature, stirring.
Toss ham with reserved parsley and divide among jars. Pour gelatin on top and chill until set, at least 1 hour.
Whisk together mayonnaise, mustard, vinegar, 1/4 teaspoons salt, and 1/4 teaspoons pepper in a large bowl. Stir in celery, cornichons, and potatoes.
Pulse peas with marjoram, oil, 1/2 teaspoons pepper, and 1/4 teaspoons salt in a food processor to a coarse mash.
Layer peas, then potato salad, over ham.
