Jambon

Jambons (from French jambon 'ham'; Irish: siamban) are square pastries filled with cheese and chunks of ham. They are a ubiquitous deli item in Ireland and parts of the UK. The product emerged during the 1990s as part of a broader movement towards "food to go". The multinational bakery company Délifrance claims to have adapted and launched the jambon as a new product in the Irish market in 1997.

Twenty million jambons were purchased by Irish consumers in 2020. Following the trend of meat-free sausage rolls, vegan jambons have also been available since 2020. These pastries are produced in a similar manner, using meat substitutes and cheese analogues for the filling.

Jambons are known in France as paniers feuilletés au jambon et au fromage (puff pastry baskets with ham and cheese).
