How to make: Orgeat Syrup

Hello and welcome back!
.

This is a video I shot to complement the Tia Mia cocktail video I was having issues with to further elaborate on what exactly is Orgeat and better yet where it originates from. I do plan on posting that video but the release date is TBD.

I plan to better utilize my Youtube channel, so from now on until there is a shift in structure, I'll breakdown ingredients and different unique liqueurs on my Youtube page and will give previews on my IG page

The word Orgeat (pronounced or-zhat) has French origins that roughly translate to "Barley Water", according to Paul Senft's article "In Honor of Orgeat". Since there were no refrigeration units in the 18th Century (when the origin of this syrup is traced back to), water and oil were the go-to combinations to obtain the status of emulsion that were shelf-stable when kept at room temperature.
At some point in time, barley was switched out for almond as its oil content also reach a status of emulsion with water. Bottom line, this was the form of thinking that lead to finding ways to create alternatives to milk that could be more shelf-stable. With the rise of cordials later on, with time became more prevalent, the same school of thought was used to tinker with orgeat with the addition of orange rose water along with traces of alcohol to add dimension to this ingredient and the cocktails that utilize this ingredient.

The first recorded use of orgeat in a cocktail in written history can be traced to Jerry Thomas' 1862 Bartender's Guide. The cocktail drink in question is the Japanese Cocktail, in which modern cocktail historian David Wondrich further researched and claims a connection to the creation of the cocktail and the first Japanese Diplomatic mission to the United States that took place in June of 1860. An individual who was part of that Japanese legation was a man called Tateishi Onojirou Noriyuki a.k.a. “Tommy.” Tommy was suspected to be an active imbiber that visited the bars of New York City as part of that Japanese Diplomatic visit, and more likely than not stopped at Jerry Thomas' bar and Thomas commemorated this visit with the Japanese Cocktail.
