Pretty sure I saw Pho Saigon Basil in Belmar selling some last summer. You might try calling them to ask.
But I would suggest buying from the farm Huy Fong screwed over: https://www.amazon.com/Underwood-Ranches-Sriracha-Artificial-Preservatives/dp/B09HZ6YPPH
I bought a few bottles of Underwood Ranch sriracha after learning about the Huy Fong fuck-up and can confirm it's fantastic, you won't be disappointed.
The company they tried screwing over makes their own sriracha now. It's very good. https://www.amazon.com/Underwood-Ranches-Sriracha-Artificial-Preservatives/dp/B09HZ6YPPH/ref=sr_1_5?hvadid=390252716344&hvdev=c&hvlocphy=9030890&hvnetw=g&hvqmt=e&hvrand=633670600158301610&hvtargid=kwd-832276397228&hydadcr=7662_9903423&keywords=underwood+ranches+sriracha&sr=8-5
I recommend giving Underwood Ranch's sriracha a try, it's my personal favorite. Underwood was Huy Fong's jalapeno supplier until HF pulled out on their deal, which is why it's hard to find their product these days. Go straight to the source!
Not sure if/when you are going to see it again, but I found this bit in an article about the lawsuit that might be of interest:
Meanwhile, Underwood Ranches continues to grow five different varieties of peppers, Haas avocados, and a wide variety of row crops for a wide variety of retailers. It also has its own line of hot sauces, including a spicy BBQ, verde, and—for real—sriracha.
I've not had it to compare, but if it uses the same peppers it might be the most similar, and Amazon has it for way less than the black market.
