In a dry, heavy-bottomed pan or skillet, add the coarse semolina. Toast over medium-low heat, stirring constantly, until it turns a light golden-brown and smells nutty. This should take about 15-20 minutes. Be careful not to burn it.
Once toasted, remove the semolina from the pan and set it aside to cool slightly.
In the same pan (or a clean one), melt the butter over low heat. Once the butter is fully melted, add the honey and stir well to combine.
Bring the butter and honey mixture to a light simmer, then immediately remove from the heat.
Gradually add the toasted semolina to the warm butter and honey mixture, stirring continuously with a wooden spoon or spatula. The mixture will thicken and become a soft, pliable paste.
Pour the warm Tamina into individual serving bowls or a single decorative plate. Use the back of a spoon to flatten the top.
Decorate the Tamina with a dusting of cinnamon, often in a decorative pattern, and sprinkle with toasted almonds or pistachios. Serve immediately while it's still warm.
