What does gelato strain?

Excuse me, but I'm a bit confused by your question. Typically, the term "gelato" refers to a type of Italian ice cream that is known for its creamy texture and rich flavors. It's not a strain in the context of biology, medicine, or finance, where the term "strain" is often used. However, if you're asking about a specific use of the word "gelato" in a non-traditional sense, or if there's a pun or metaphor at play, I'm afraid I would need more context to provide an accurate answer. Could you please clarify what you mean by "gelato strain"? Are you referring to a specific product, service, or concept that uses the term "gelato" in an unconventional way? Or is there a different word or phrase that you might have meant to use instead?
