Thai Green Curry Recipe

THAI GREEN CURRY

Ingredients

1 tbsp vegetable oil
2 tbsp green curry paste (according to taste)
1 tbsp soft dark brown sugar
1-2 thick stalks lemongrass, fat ends bashed with a rolling pin (optional)
750g skinless, boneless chicken, cut into chunks (use breast and/or leg meat)
6-8 lime leaves, torn into pieces (if unavailable, use the grated zest of 1 lime)
400ml coconut milk
good shake Thai fish sauce or light soy sauce
small handful coriander, roughly chopped
1 lime, juice only

Method

1. Heat the oil in a wok or large frying pan. Add the green curry paste and sugar and cook over a fairly high heat for about a minute, stirring with the lemongrass, if using. Reduce the heat slightly and stir in the chicken pieces and lime leaves or zest until coated in the paste. Add the coconut milk, fish sauce or soy sauce and bring to a simmer, cooking for 25-30 minutes until thickened slightly. Stir in the coriander and lime juice. Check for seasoning, adding more fish sauce or soy sauce if needed.

2. The curry is now best left to sit for a few minutes so the sauce becomes creamier. You will also taste the true flavours of the curry paste ingredients when it's slightly cooler. Serve with lots of fragrant Thai jasmine rice.

THAI GREEN CURRY PASTE

Ingredients

4-6 medium green chillies, de-seeded and roughly chopped
2 shallots, roughly chopped
5cm/2in piece of fresh ginger, peeled and grated
2 garlic cloves, crushed
small bunch of fresh coriander, stalks and roots attached if possible
2 lemongrass stalks, chopped (if unavailable, use 2 tbsp dried)
1 lime, grated zest and juice
8 kaffir lime leaves, torn into pieces (if unavailable, use the grated zest of
1 extra lime)
2.5cm/1in piece galangal, peeled and chopped (if available)
1 tbsp coriander seeds, crushed
1 tsp ground cumin
1 tsp black peppercorns, crushed
2 tsp Thai fish sauce or light soy sauce
3 tbsp olive oil

Method

1. Place all of the ingredients in a food processor and blitz to a paste. Use straight away or store in a jar in the fridge for up to 3 weeks. This quantity is enough for a curry for 8 people.

Tip:

When your curry is cooked, if you think it is too spicy, add some more sugar; if it isn't spicy enough, fry a little more curry paste in some oil for a minute or two and add to the sauce.

Retaining WhiteSpace When Posting Python Code

To post python code in a blog (html) and retain the line whitespace that is required in order for the code to remain unambiguous, simply enclose your code within pre html tag block.

The 'pre' tag yields a fixed-width (monospace) font, and preserves spaces and line-breaks.

<pre>

def doStuff(i):
    print()
    for z in range(i):
        print(z)    

c = 4

for z in range(c):
    doStuff(z)

</pre>
