Best results are obtained if the condensed milk is used at room temperature, and on the day it is freshly made. However, any extra can be stored. Store the unused sugar free sweetened condensed coconut milk in an airtight container that can go from cold to hot. The content will keep in the refrigerator for one to two weeks. Note that the homemade condensed milk will harden, especially if stored in the refrigerator. To reliquify, boil some water in a small and deep sauce pan. Remove the sauce pan from heat and place the container of the condensed milk into the hot water. Stir occasionally as the solid is turning back into a liquid. Stirring is important in order that all the ingredients stay emulsified. When the condensed milk has almost completely become fluid, remove the container from the water and stir to combine. Use at room temperature. CAUTION: Heating directly in a pot or in a microwave will change the taste and/or the texture.

Regarding use of sweeteners: In the video I use Lakanto monk fruit-based sweetener, which is an erythritol/monk fruit blend. This sweetener is a 1:1 ratio in sweetness with table sugar. Alternatively, you could use a stevia-based erythritol blend sweetener of your choice, such as Swerve or Sukrin. These two products, as well as most stevia based sweeteners, are also 1:1 ratio with table sugar, in sweetness. If you do not wish to use an erythritol-based sweetener, birch xylitol is also very good, as it too is 1:1 ratio, but do not buy the corn-based xylitol. You should also know that there is a cautionary note when using xylitol: ALWAYS keep any food you make with xylitol away from pets, as well as the bowls with any ingredient that has xylitol in it, because xylitol is toxic for pets (especially cats and dogs).

If it is available in your area, an allulose product, which is a rare sugar, is an excellent all-natural substitute sweetener. It is excellent for cooking and baking especially. However, it has about a 0.7:1 or 0.8:1 ratio of sweetness as compared to table sugar and the above-mentioned sweeteners, so you may have to adjust by adding more allulose (about 1/4 cup more per cup of stated sweetener) to achieve the same degree of sweetness.

If you are a diabetic please note that both xylitol and allulose will have a low but non-zero glycemic response, so use with caution, and after doing your own reading and research and, if need be, consulting your medical health advisors.
