Google-search – Is it possible to search for a specific HTML tag within a site using a search engine

Try a plain Google search with terms recipes using tomato sauce. After the initial results are returned, you can click the "Recipes" button on the left to be more selective.

Added via edit:

As per the discussion in the comments below, you can get pretty much the non-tomato-sauce recipe results wanted by using this "tomato sauce" without tomatoes search.

There are many ways to accomplish this.

dance class near Andheri, Mumbai, India will return listings above the search results

A second way would be to point your browser to google.co.in then set your location in the sidebar. The closest I got was "Andheri East, Maharashtra" (which seems to be the correct way to phrase it).

Web results itself are harder, how would one check whether a site that has dance classes is located in Andheri East, Maharashtra without checking some location within the text displayed on the site?
