I dunno know about the binding (maybe you can use method_missing +   
Binding.of_caller)

but one to get the code (well the ast, which is pretty darn close) is  
do something like:
require 'parse_tree'

def recipe(name, &blk)
    class A; end
    A.class_eval { define_method(:code, &blk) }
    pt =  ParseTree.new
    sexprs = pt.parse_tree(A)
end
