The super easy sugar-free homemade preserved stem ginger is deliciously sweet and spicy! It's great in keto & low-carb recipes, cocktails or by itself as a healthy sweet treat!
Add sliced ginger, sweetener and water to a pan and bring it to a boil, stirring until the sweetener is completely dissolved. Bring down the heat to very low, cover the pan, and let it simmer.
Check the the pan for the water level at about every 30 minutes. If the water is not covering the ginger pieces anymore, add more boiling water.
Simmer until the stem ginger gets softened. You can check for doneness by piercing one with a fork. It should take 2 to 3 fours, less time for ginger that has been frozen.
Preserved ginger in pressure cooker
Boil the water. Add the hot water, sweetener and the ginger to the pressure cooker or instant pot. If needed, add more water to reach at least the "minimum" level mark inside the pan. Stir well to dissolve the sweetener.
Cook fresh ginger for 60 minutes on high pressure, previously frozen ginger for 40 minutes. Let pressure release naturally.
Notes
*Freezing the ginger for a few days before using will make it soften much faster. If using fresh ginger, it takes about 2-3 hours in a regular pan and 60 minutes in a pressure cooker/instant pot. It can take about half this time for previously frozen ginger.**Allulose or xylitol are the preferred sweeteners for the ginger syrup. Erythritol can be used, but it might cause some crystallization in the syrup.Store the ginger in an airtight jar in the fridge, fully submerged in the syrup.
