Is adding guar gum and lecithin alone enough for homemade ice cream?
@TLSO All industrial/semi-industrial processes involve aeration to make the ice cream fluffy and scoopable. So, you have to introduce some air continuously in the mixture until it sets (using an ice cream maker probably). This trick will make scoopable ice cream just with milk, cream, sugar and optional essence of your choice with no need to add gums or alginates.
It is equally important that the tub of ice cream is returned to the freezer as soon as you have scooped out the ice cream. Because melted ice cream will harden and will need thawing as there is less/no air inside the mixture.
Try and let me know.
