Fifteen minutes and it tastes like a takeaway, which for a tin of crab and a tin of corn is a good return.
- Sesame seeds toasted dry, two minutes, out.
- Slake the cornflour to a smooth paste with cold water. This first, always.
- 800 ml water, stock cube and ginger to a simmer. Half the sweetcorn crushed in, half left whole, the crushed half thickens and sweetens the broth.
- Cornflour paste stirred in, two minutes until it goes silky.
- Off the heat, drained crab folded through with the soy sauce.
- Sesame over.
Crab is delicate and expensive; boiling it is the one way to waste it.
