Anyway, with the dried lime and the dried lime powder (using which is a lot less finicky work than manually separating the black bits from the whole dried limes, I can tell you), I made lubia polo.

Dried lime tapped open with a hammer

Then pulled apart by hand

The black interior contents scraped out (on the right) and the discarded lime peel (left)

Readymade powdered dried lime - a much simpler option
And then I suddenly realised that the post had been hanging fire for at least 10 days, and it would be perfect for Zlamushka's "Tried and Tasted" event that's currently happening - assuming I'm not too late with my offering.
This baked green-bean and potato rice has the least amount of spices and seasoning that I've ever seen... and yet the end result is so INCREDIBLY flavourful! I followed pretty much the same method as Nupur, except that instead of garam masala I used a couple of pinches of my extremely potent, aromatic, home-made dhansak masala!
I have to admit that my lubia polo did not turn out as beautifully shaped as Nupur's, nor did it hold together nicely. But that was because I didnt - dont - have the right-shaped non-stick pan, nor even a heavy-bottomed non-non-stick (how else do you say it?) pan... so I improvised with a shallow vessel I use in the pressure cooker. It was too thin so the potato slices at the bottom got a bit burnt and the rice didnt get a chance to crisp up. But, like I said, it was fantastically tasty, even if not picture-perfect to look at. In any case, if you're looking for picture perfection, the blog to go to is Nupur's! :)
Recipe for: Nupur's lubia polo

Ingredients:
1 cup basmati rice, washed and soaked for 15 minutes
2 cups green beans, halved
1 onion, chopped
1 potato, peeled and sliced thin
1/2 cup tomato puree
1/2 tsp turmeric
1 tbsp olive oil
1 tsp butter
Salt to taste
1 tsp garam masala/pav bhaji masala/dhansak masala
1 htsp powdered dried lime OR 1 tbsp fresh lime juice
Method:
1. Boil the rice in 2 cups of lightly salted water till almost done. Drain well and reserve.
2. Heat the olive oil in a skillet and fry the chopped onion till soft and light brown.

3. Add the green beans and saute for a few minutes,

then add the tomato puree and whichever masala you're using.

4. Simmer the beans till tender, then add salt to taste. The sauce should be fairly thick now. Add 1 heaped tsp dried lime powder, mix and set aside.
5. In a medium deep non-stick pan, melt 1 tsp butter. Stir in 1/2 tsp turmeric and water. Layer the bottom of the pan with the thinly sliced potato.

6. Put half the rice over the potatoes,

then pour over the green bean mixture,

and finally the rest of the rice.
7. Cover the pan and leave on medium heat for 10 minutes, then lower the heat to its lowest point.

Place a clean dish towel under the lid and fold the hanging edges back on top of the lid.

9. Cook on low heat for 20 minutes or so, then let the pilaf rest for 10 minutes.
10. After the resting time, invert the pan onto a serving dish. The pilaf should unmold itself whole - but if it doesnt (like mine) dont worry... it will still taste delicious!
