For the chili paste, cut off the stalk of the chili peppers, remove the seeds and cut the peppers in half lengthwise. Bring to a boil in cold water. Pour off the water. Repeat this process at least two more times. In this way, the chili will become milder. Peel the chili peppers and puree them finely.
In the meantime, clean the celery well and cut it into coarse pieces. Peel the onion and cut it into coarse pieces as well. Peel the garlic clove and ginger. Remove the seeds from the chili pepper. Squeeze the limes.
Finely puree all ingredients (preferably in a stand mixer). Strain through a sieve and refrigerate the tiger milk until further use.
