Such a simple recipe and so delicious...but we agree with others about the Simple Syrup and include just 10ml. Each to their own, of course, and the human palate is a wondrously (is that a word?) varied thing.

Angostura, I think, I optional. Just made it without angostura and it is absolutely great

I have already tried it with tenqueray gin and vaious proportions of sugar and angsotura.
This is absolutely must try thing. Although it requires fine-tuning of proportions. I personally liked it with less sugar, and much less angosutra because it kills taste of pine that gin gives

I’m an amateur so don’t mind me but I have being trying do to it twice with the same ingredients but I get it orange… Any idea why and how I can fix that??

Gorgeous. Just gorgeous. I definitely think it needs a little less sugar (or to go up to 60ml/30ml gin/lemon) and the angostura is a must.

Tangy and refreshing. Mine went down in a couple of glugs! Dangerous!

Made it with Drumshanbo Irish Gin in honor of F. Scott Fitzgerald's birthday. "This Side of Paradise" is the book that convinced me I wasn't missing anything by not attending Princeton. Didn't understand the call for Angostura bitters in a gin sour, though, so I used Fee Bros. West Indian Orange Bitters with very good results.

Made one with a local dry gin and some mugolio/pinecone syrup I made, thinking it would be a good way to highlight the pine flavor. It was perfect! Great drink, I think I prefer my gin sours without the egg white.
