Extra Strong Lime Mortar Takeaway....

For strong lime mortars you can either use a NHL which includes naturally occurring or added minerals to give a stronger chemical set. You can also add a pozzolan such as fly ash or brick dust for the same effect.

However, I've not heard of adding rice before:

"The results showed that the organic-inorganic compound was made possible by amylopectin, a type of polysaccharide, or complex carbohydrate, found in rice and other starchy foods."

I wonder if potatoes would work just as well? Might be a good use for that awful powdered potato stuff.
