Dots (...) with variable title

I need to run a function of type

f <- function(...) {
  l <- list(...)
  l[["hortela"]]
}

x <- 'hortela'

If we do

f(hortela = 1)

We have the result 1 , which is what we expect.

How do I call f() using x instead of writing hortela manually?

PS: I do not want to change the f() .
