Scientists are diligently looking for other genes that may be involved in ALS, but currently, there is no other genetic test that will identify ALS in families. Therefore, the determination that an individual has the inherited type of ALS is typically based on family history rather than a genetic test.
Jakub Krystof Rad invented the first sugar cubes in the 1840s at a sugar refining plant in Dacice, a small Moravian town in what is now the Czech Republic. These early cubes were made primarily of beet sugar, and in modern times, either beet or cane sugar is considered acceptable.
If you didn't already, try using a sugar cube with it. Traditionally, a sugar cube is placed on a slotted spoon (an absinthe spoon) and the water you add is poured over the sugar cube. The sweetness takes a little of the harshness from the wormwood and the intense anise flavor and makes it a little smoother. The bottom line is that it is primarily flavored by anise. As a result, if you don't like the flavor of black liquorice, you are NOT going to like absinthe.
