Loops[edit]

The PGF/TikZ extension provides the \foreach command.

\usepackage{tikz}
% ...

\foreach \i/\q in {wheat/50g, water/1L, yeast/2g}{
  \noindent\i\dotfill\q\\
}

If you are only using \foreach and not drawing graphics, you may instead use the pgffor package directly.

Alternatively you can check out the multido package.
