4 whole lobsters (about 1 1/2 lb each)

For The Lemongrass Chive Butter:
1/3 cup unsalted butter melted
juice of 1/2 lemon
grated zest of 1 lemon
2 stalks, lemongrass, tender inner part only, finely chopped
2 Tbsp. chopped fresh chives
Fresh cracked black pepper

Preparing The Lemongrass Butter:
1. Combine the butter with lemongrass in a small saucepan on low heat. Let simmer gently over very low heat, about 8-10 minutes. With a spoon, skim off any solids that have collected on surface of butter.

Preparing The Lobster:
1. Bring at least 5 L (20 cups) water to a boil in a large pot. Season well with salt.

2. Cook lobsters for 8 minutes and remove from water immediately.
(Cook 2 lobsters at a time to keep water at a boil)

3. Meanwhile get BBQ ready by heating on high and brushing grill until very clean.

Remove claws and heads from the lobsters, discarding heads, or keep for stock.

4. Crack claws with hammer or back of heavy knife just until split but shell is still in tact.
Split tails in half lengthwise with a sharp heavy knife or shears.

5. Meanwhile brush tails, flesh side, with a little melted butter and place, shell side up, on grill along with all the claws. Grill about 5-6 minutes with lid up. Tails should have grill marks. Remove immediately.

6. Add the chives, lemon zest, juice and cracked black pepper to warm butter, just before serving.

7. Serve lobster with warmed butter and plenty of bibs. Don't worry about the mess!

Tips:
Always put the live lobster into boiling water and remove immediately after cooking time is up.

If you are uncomfortable cooking live lobsters, most fish stores have a steaming service.
You just have to tell them you are grilling them after so they will slightly undercook them.

The live lobster should be bought the day of cooking and keeps best wrapped in newspaper in a box in the fridge. If the lobster is not moving when removed from fridge, it cannot be eaten.

Options:
To simplify the recipe even more you can buy just lobster tails that have more meat and no claws to worry about. You will pay a hefty premium for your convenience.
I love the mess of eating lobster - it is part of the ritual.
