Is this how you spell jalapeno?

In an English spelling bee, you would say j-a-l-a-p-e-n-o because the tilde N (ñ) has no name in English and is considered punctuation of the loanWord.

In Spanish, the ñ has a separate name (enye, pronounced ayn-yay), but of course all the other letters are pronounced differently as well.

La palabra jalapeño se escribe (hablado) "jota-ah-ele-ah-peh-eh-enye-oh."

(hoh-tah, ah, ay-lay, ah, pay, ay, ayn-yay, oh)
