How do I anchor text from one column to text location in another column?

Questions
1

I would like to have a grid layout with two columns in which the first column has some instructions and the second column are ingredients for the instruction. This type of thing is common in many recipe/cooking books. For example, if I mention apples in an instruction step on the left column, I’d like the number of apples to appear in the right column (e.g. 2 apples) but at the same vertical location that apples are mentioned in the left column. If there are multiple ingredients mentioned, I’d like to stack them in the right column.

This behavior is similar to the margin notes functionality provided by the drafting package. However, I’d like to do something similar within a grid layout in the document body instead of the document margins.

Is this possible?

Could you use a grid with two columns? (instructions in the left column, ingredients in the right one)

I can easily create a two column grid layout and put ingredients on one side and instructions on the other. However, I’d like an ingredient to occur at the same vertical position in the ingredients column when it is mentioned in the instructions. See how margin notes work in the drafting package.

I see. What about the following?

#let ingredient(it) = text(red, it) + sym.zwj + context {
  let leading = 1em.to-absolute()
  let (x, y) = here().position()
  let prev = query(selector(<ingredient>).before(here()))
  let dy = if prev.len() == 0 {
    0pt
  } else {
    let prev-y = prev.last().location().position().y
    calc.max(0pt, leading - (y - prev-y))
  }
  box([#place(bottom+left, dy: dy, dx: 12cm - x, it)<ingredient>])
}

#block(width: 8cm)[
  #lorem(8) And #ingredient[carrots] and #ingredient[cucumber]. #lorem(10)
  #lorem(20) And #ingredient[ginger].
]
