It reaches a point where it has economy of scale and specific taste profile developed that it is very hard for others to break into the market. Similar to bake beans for those living in UK.
The cost of ingredient is so low in the overall of things, restaurants, owner, vendors or whatever are not willing to switch ingredients and risk losing their customers. Tabasco is similar because majority of their business actually resides in Food Services sector and not consumers. The basic rule of thumb in Food offering, dont FUCK with your recipes.
I remember when I was still in the Food sector I was trying to import and distribute Sriracha for years in the late 00s and very early 10s. Every time the answer has been not enough capacity. Demand outstripping Supply in most of their important / domestic ( US ) market. Importers have to rely on non-official parallel import channels. Somehow I think it went internet viral by mid 10s, which in turns generate further interest. And a whole positive feedback loop was formed. Worth noting is that these things takes a long time to make. I dont know about Sriracha but Tabasco takes up to three years. Once you factor in capacity planning and sourcing of quality chillies ( and assuming yields are good ), that is why supply takes time to catch up.
Unfortunately these type of investment takes a very long time and are not something VC likes to invest in. But for me they are sometimes far more interesting and fascinating than most tech.
