The UK teaspoon is about 20% larger than the US teaspoon. A recipe calling for 5 UK teaspoons would need 6 US teaspoons.
Assuming UK and US teaspoons are the same — the UK teaspoon is about 20% larger. This matters in precise baking.
Modern UK recipes increasingly use metric (5 mL teaspoons). When following older UK recipes, a UK tsp ≈ 6 mL.
