How To Make The Crispiest Roast Potatoes.

Making super crispy roast potatoes is a four stage process!

Soaking The Potatoes.

The first step is prepping the potatoes. After peeling, they need to be cut into evenly sized pieces that aren’t too small & not too big. Cutting a large potato into quarters or a smaller one into two or three pieces is a good guide to follow.
Once you’ve got a load of cut roasties, they need washing until the water runs clear followed by a soak in cold water for at least an hour. This removes a lot of the starch from the potato which in turn will make the cooked spuds crispier!

Par Boiling.

The next step is to boil the potatoes in a pan of heavily salted water until the outer layer of the potatoes starts to soften. The aim here isn’t to fully cook the potatoes at this stage. 10-15 minutes of boiling is usually enough time.

Coating The Potatoes.

Once the roasties have been par boiled, the next job is to drain them in a colander for a couple of minutes. The potatoes are then returned to the empty pan, semolina & cornflour are added then the pan is shaken (with the lid on!) until the potatoes are all covered & the outside are roughed up.

The roasties are then carefully transferred to a roasting tray & a mixture of hot fats, garlic & herbs are poured over. A generous amount of salt & pepper is also added/

Roasting.

The final step is the roasting. A raging hot, pre heated oven is key to crisping up the potatoes. Giving the tray a good shake every 15 minutes or so helps cook the spuds evenly.

Notes

Cooking In An Aga.

Use the boiling plate to par cook the roasties then roast in the centre of the roasting oven.
If you don’t have any goose or duck fat, use extra veg oil.
Make sure not to overcook the potatoes when boiling them – only the outside should be soft.
The recipe for the confit garlic in this recipe can be found here.
Make sure to soak the potatoes for at least an hour before boiling. This removes any excess starch from the potatoes, making them crispier once roasted.
