Pour the cream into a pint-size jar with a tight-fitting lid.
Lay the cardamom pods on a flat surface and cover with a clean kitchen towel. Gently pound with a heavy mallet to crack the pods open then add to the jar of cream. Tightly affix the lid and shake to combine. Refrigerate for 24 hours.
Remove the cream from the fridge and strain through a fine mesh sieve into a large mixing bowl situated over a large bowl of ice. Whisk by hand until the cream forms stiff peaks, about 5 minutes. This can also be done in with an electric hand mixer if you do not wish to do it by hand.
