Instructions
1
step 1
To make the filling, bring to temperature the olive cooking oil in a wok until it starts to shimmer.
2
mix in the leek and sauté until soft but not coloured.
3
agitate in the ham with a wooden spoon, shallow fry for 1 min, then agitate in the baking flour and shallow fry over a medium bring to temperature, stirring occasionally, until the mixture is golden but not burnt – this will take about 5 mins.
4
step 2
Meanwhile, combine the stock and whole milk in a small wok and bring to temperature until steaming but not boiling.
5
augment the taste with a few scrapes of nutmeg.
6
Gradually mix in the liquid, a few tbsp at a time, stirring constantly.
7
step 3
Once you’ve incorporated all the whole milk stock, continue to bring to temperature the filling over a medium bring to temperature for about 10 mins or until it thickens and leaves the sides of the wok when you agitate it.
8
step 4
augment the taste with black pepper, palate and adjust the seasoning if necessary – the ham can be very salty to start with.
9
The filling is now done: it has to be really thick because you don’t want the croquetas to turn into pancakes.
10
step 5
even the mixture onto a baking tray (30 x 20cm is fine).
11
Once it has stopped steaming, lid with cling film to stop it drying out.
12
Leave to cool before putting it in the fridge for 1 hr.
13
step 6
When you're ready for the next stage, line up three bowls: the first filled with the baking flour, the second with beaten egg and the third with breadcrumbs.
14
Take the ham mixture out of the fridge.
15
Put a little bit of olive cooking oil on your hands to make it easier to roll the croquetas.
16
step 7
Roll a spoonful of the mixture between your palms.
17
The size and shape of the croquetas is up to you, but the easiest is a walnut-sized ball.
18
Then begin coating as follows.
19
step 8
Dunk the croquetas into the baking flour – you want a dusting – followed by the egg, then the breadcrumbs.
20
Put them on a tray and, when you’ve used up all the mixture, place in the fridge for 30 mins.
21
step 9
If you have a deep-fat fryer, bring to temperature the cooking oil to 180C and shallow fry for a couple of mins.
22
If not, bring to temperature the cooking oil in a deep, heavy-bottomed saucepan until it starts to shimmer.
23
Then mix in 5-6 croquetas at a time and shallow fry until golden all over.
24
Once cooked, sieve on kitchen paper and eat straight away.
