Ingredients

  • 1 kg potatoes (2 lbs) approx 8 see notes
  • 1/3 cup olive oil
  • 4 sprigs fresh rosemary (optional)
  • 4 unpeeled garlic cloves - flattened slightly (optional)
  • salt to taste
  • 1/4 tsp baking soda / bicarbonate of soda see notes

Instructions

  • Preheat oven to 210c/410f.
  • Bring a large pot of water to boil, then add bicarb soda - it will fizz a little.
  • While the water is coming to the boil, peel your potatoes.
  • Once boiling, add the bicarb soda - it will fizz a little. Then carefully add the potatoes, and boil for 20 mins or until very soft. 
  • When the potatoes have about 10 minutes to go, pour the oil into a metal roasting tin, and place in the oven to heat.
  • When potatoes are soft, drain well then return to the pot. Give them a mix around in the pot to rough them up, if they break apart a bit that's fine too.
  • Carefully add potatoes to now-heated oil, and turn well to coat them completely.
  • Bake for 1 - 1 1/4 hours, tossing again about every 15 mins (add rosemary and garlic cloves with approx 15 - 30 minutes to go if using). 
  • Discard rosemary and garlic, add salt to taste and serve immediately.

Notes

The variety of potato to use for this recipe needs to be "starchy" or "floury" - here in Australia most of the major supermarkets sell dirt brushed potatoes (sebago) which is what I used. 
I find that approx 130, 140 (ish) grams per potato is just the right size, and I serve 2 potatoes per person. Extra crispy potatoes have calories that don't count!
If the potatoes break up a bit when you are roughening them up, that's ok - as you can see the smaller ones get lovely and super crunchy!
Baking soda and bi-carb soda or bicarbonate of soda are the same, it just depends what country you live in!
