Weighing in two years later to say that for the Dynasty Margarita page, and for that page alone, Patron Citronge is indeed the default triple sec. I'd honestly never heard of it, far less added it to my ingredients list—in fact when I saw it I assumed it was yet another category of orange liqueur, and I have I think nine bottles across seven categories already, so I did raise an eyebrow.
Reading this I was like, Yuck... but maybe Yum? Turns out it makes the tastiest version of this combination of ingredients I could have likely imagined. Yum.
Was a little worried my expectations were setting me up for disappointment but no, total game-changer. I was not always the lofty paragon of moral virtue I am today, and may indeed have shameful memories of using egg white in the distant past; this is in my opinion just better. Same in terms of texture and dilution, smells and tastes like nothing, foams if anything better. Massive upgrade, and not just from other vegan alternatives.
