Here's a recipe from this German book about Green Tea. Pretty sure I got the translation right

500g fresh green beans
2 crushed cloves of garlic
4 teaspoons gunpowder green tea
4 cups water

Cook the green beans in a pot.
Make the green tea with the water.
Remove the tea leaves.
Roast the garlic in a lightly oiled pan and when it is golden add the tea.

Mix well.

Put the beans into a bowl and pour the tea marinade over them - serve immediately.

I tried this recipe the other day and it's very good! It's my first experience cooking with tea - I've eaten tea leaves before but never used liquid tea for cooking.

Try it!
