* 4 medium to small Leeks, liberally trimmed, peeled and cleaned
* Sea salt and Freshly ground black pepper
* Pinch of fresh Thyme leaves
* 150g cooked Ham - the thinner the better, thick ham does not roll well!
* 100g Cheddar cheese for the Cheese sauce
* ¾ pint of Milk [354 ml]
* 2 tablespoons Butter
* 2 tablespoons Plain flour
* 4 tablespoons Panko Breadcrumbs
* 25g Cheddar cheese to top
* 25g crumbled Blue cheese (optional)

===Method===
* Ensure the Leeks are properly cleaned
* I've used small gratin dishes so had to halve them but you can leave them whole
* Boil the Leeks in lightly Salted water for about 8 minutes or until softened - they can also be microwaved, see below.
* Drain well.
* Meanwhile, to make the Cheese sauce, melt the Butter with a pinch of Black pepper and stir in the Flour once melted.
* Whisk the Milk in and bring to a Simmer, don't Boil. Once Simmering, whisk well, add 100 g of the Cheddar and once melted, remove from the heat.
* Roll the Leeks in the cooked Ham and lay in a lightly oiled gratin dish or shallow Casserole.
* Pour the Cheese sauce over the Leeks.
* If you have the time, chilling the mixture in the gratin dishes (as pictured), solidifies the cheese sauce making it easier to add the topping, which has a tendency to sink into the hot sauce.
* Mix the Breadcrumbs and any Cheese you are using for the topping in a bowl and Crumble well, maybe add a pinch of Black pepper.
* Pour this mixture over the top and Bake uncovered at the top of the Oven at 180° C
