Begin by chopping the onion.
Heat olive oil in a medium-sized pot and sauté the chopped onion and pressed garlic until they become translucent
Next, add the grated tomatoes, water, smoked garlic powder, chopped fresh basil, fish stock cube, honey, butter, black pepper, and umami powder (optional) to the pot.
Bring the mixture to a boil and then reduce the heat to let it simmer for 10 minutes.
Add the crumbled feta cheese and the shrimps to the pot, allowing them to boil for 2 minutes.
Cover the pot with a lid and set it aside, as the residual heat from the sauce will continue to cook the shrimps. It’s important not to overcook them, as they may become tough.
Meanwhile, in another large pot, bring water to a boil and add some salt.
Once the water is boiling, add the orzo (risoni) and lower the heat to medium. Let it boil for 10 minutes or as per the package instructions.
When the orzo is al dente, check if most of the water has been absorbed. If excess water remains, strain off some of it.
Mix the shrimp sauce into the orzo thoroughly. Cover the pot with a lid and let it sit for 5 – 10 minutes to allow the orzo to absorb the flavors.
If you find that the kritharoto / orzo is too compact for your liking, feel free to adjust the consistency by adding a little hot water.
Add a finishing touch by sprinkling some crumbled feta and chopped fresh basil on top of the dish before serving.
