πŸ“ About This Recipe

A cornerstone of the British cold larder, this sandwich celebrates the marriage of salty, honey-glazed ham and the sinus-clearing heat of traditional English mustard. By using thick-cut, home-cooked gammon rather than processed slices, we elevate a humble lunchtime staple into a gourmet experience. This recipe honors the classic pub-style 'Ploughman’s' aesthetic, balancing rich butter, sharp mustard, and crisp, fresh greens.

πŸ₯— Ingredients

The Bread & Fat

  • 4 slices Sourdough or Bloomers bread (thick-cut, preferably from a fresh artisan loaf)
  • 3 tablespoons Unsalted Cornish butter (softened to room temperature for easy spreading)
  • 1 pinch Sea salt flakes (to season the butter)

The Meat & Pungency

  • 200 grams Honey-roasted gammon (thickly carved off the joint, cold)
  • 2 teaspoons English Mustard (Colman's is the traditional choice for authentic heat)
  • 1 teaspoon Wholegrain mustard (for added texture and vinegary depth)

The Larder Crisp

  • 6 pieces Cornichons (sliced lengthwise into thin ribbons)
  • 1 handful Watercress (washed and patted dry, tough stalks removed)
  • 1/2 Small Shallot (sliced into paper-thin rings)
  • 1 pinch Black pepper (freshly cracked)

πŸ‘¨β€πŸ³ Instructions

  1. 1

    Begin by selecting a high-quality loaf of sourdough or a traditional British white bloomer. Slice four generous pieces, approximately 1.5cm thick, to ensure the bread can support the heavy fillings.

  2. 2

    Place the softened butter in a small bowl and whip it slightly with a pinch of sea salt until it is creamy and easily spreadable.

  3. 3

    Spread a thick, even layer of the salted butter onto one side of all four slices of bread. Ensure you reach the very edges; the butter acts as a moisture barrier against the mustard.

  4. 4

    On two of the slices, spread the English mustard directly over the butter. Use more or less depending on your tolerance for heat, but a thin, translucent layer is usually perfect.

  5. 5

    On the other two slices, spread the wholegrain mustard. This provides a lovely visual contrast and a popping texture.

  6. 6

    Carve your cold honey-roasted gammon into thick, rustic slices. Avoid thin 'shaved' deli meat; you want substantial pieces that offer a bite.

  7. 7

    Layer the ham generously onto the slices with the English mustard, folding the meat over itself to create height and air pockets.

  8. 8

    Add the thinly sliced shallot rings over the ham, distributing them evenly for a sharp, aromatic crunch.

  9. 9

    Arrange the sliced cornichon ribbons over the shallots. The acidity of the pickles is essential to cutting through the richness of the ham and butter.

  10. 10

    Top with a vibrant layer of fresh watercress. The peppery notes of the greens complement the heat of the mustard beautifully.

  11. 11

    Season the greens with a final crack of black pepper, then place the remaining bread slices (wholegrain mustard side down) on top.

  12. 12

    Press down gently with the palm of your hand to marry the layers together. Using a sharp serrated knife, cut the sandwiches diagonally.

πŸ’‘ Chef's Tips

Always use room temperature butter to avoid tearing the fresh bread. If English mustard is too strong, mix it with a little mayonnaise for a 'Mustard Mayo' hybrid. For the best flavor, use ham that has been glazed with honey or treacle to provide a sweet counterpoint to the salt. Dry your watercress thoroughly in a salad spinner; excess water is the enemy of a good sandwich. If you have time, lightly toast the bread for 30 seconds just to give it a slight exterior crunch while keeping the middle soft.

🍽️ Serving Suggestions

Serve with a side of thick-cut salted potato crisps (chips) for a classic British texture. A cold pint of British Ale or a crisp Apple Cider pairs perfectly with the salty ham. Include a small side of pickled onions or a dollop of Branston Pickle for an extra tangy kick. For a lighter pairing, serve alongside a simple green salad with a lemon vinaigrette. A hot cup of English Breakfast tea is the traditional non-alcoholic accompaniment.
