Toast and Simmer the CardamomIn a small saucepan over medium heat, toast the crushed cardamom pods for 30-45 seconds or until fragrant. Add the water then bring to simmer, then reduce heat to low. Simmer on low for 20 minutes, or until water has reduced by about half.
SteepRemove pan from heat, cover, and allow the cardamom to steep for an additional 30 minutes while the liquid cools.
Strain and add sugarStrain the liquid through a fine mesh strainer to remove the cardamom.Add the cardamom-infused water, which should be about 1 cup*, into a small mixing bowl. Add the sugar and stir until it's fully dissolved, about one minute.*If you've increased or decreased the original recipe, you should have about half the liquid you started with.
StoreTransfer to an airtight storage container. Store in the fridge for up to four weeks.
Notes
Instead of using granulated white sugar, you could use demerara or brown sugar. You might need to increase the amount of cardamom to achieve the same intensity of flavor. If you want a stronger cardamom flavor, double the amount of cardamom. Leaving the cardamom in overnight can result in a bitter flavor. Storage: Use a funnel to transfer the syrup to a storage bottle. It will stay fresh in the fridge for about 4 weeks and can be frozen for up to six months.
