If you like the taste and the scoville level of tabasco sauces: “Fuego” has a very similar series to the tabasco series. And it tastes a bit less vinegar.

e.g. “Fuego Hot Jalapeno” https://fuchsgruppe.shop/fuego/produkte/salsas-co./

Available e.g. at Edeka Germany. They deliver everywhere in EU.

That’s a good basis. With spanish knowledge you have a bonus in Spain, Andorra, Gibraltar, Italy and Switzerland.
