Glycemic Index
GIA low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Omani mishkak of beef cubes marinated with cumin, coriander, turmeric, and tamarind, then grilled on skewers over charcoal.
Mishkak is the scent of Omani markets in the evening, meat cubes marinated with spices and tamarind and grilled over charcoal in front of passersby until their aroma wafts out.
We make it at home the way it is sold in the alleys, marinating it well and grilling it quickly so it stays tender, then wrapping it in thin bread with garlic sauce.
In a bowl, mix the tamarind paste with the crushed garlic, ginger, cumin, coriander, turmeric, paprika, black pepper, lemon juice, oil, and half the salt until the marinade is smooth.
Add the beef cubes to the marinade and toss until fully coated, then cover the bowl and leave it in the refrigerator for at least two hours or a whole night so the flavor penetrates and the meat becomes tender.
Arrange the meat cubes on the skewers slightly touching and sprinkle the remaining salt over them, leaving a small gap between one piece and the next if you like them more charred.
Grill the skewers over hot charcoal or a hot grill, turning them every two minutes for about ten to twelve minutes until they brown on the outside and stay tender inside, brushing them with a little marinade while grilling.
Serve the mishkak hot with thin bread (rashoosh), garlic or tamarind sauce, and slices of lemon and onion.
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.
A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.

The most common problems when preparing Omani Mishkak (Grilled Meat Skewers), and how to fix them:
Extend the marinating and grill over high heat for a shorter time, for long grilling dries out the meat, and choose cuts with a little fat.
Wipe off the excess marinade before grilling and keep the skewers slightly away from the direct embers, for the sugar in tamarind burns quickly.
Cut the meat into medium cubes and leave it in the marinade longer, for large pieces and a short time keep the flavor on the surface.
Keep the raw marinated meat in the refrigerator for up to two days before grilling, and the grilled meat keeps for up to two days and is reheated gently so it does not dry out.
Freeze the meat in its marinade for up to a month in an airtight bag, and thaw it in the refrigerator before grilling; this is a practical way to prepare it ahead.
| Original Ingredient | Tested Substitute | Ratio | Flavor Difference |
|---|---|---|---|
| beef | lamb or chicken | same weight, 700 g | Lamb is richer and stronger in flavor, and chicken is lighter and cooks faster and needs a shorter marinade |
| tamarind paste | pomegranate molasses or extra lemon juice | same amount, 30 g | Tamarind gives the distinctive acidity and tenderness, and the substitute comes close to the effect |
| paprika | hot chili pepper | to taste | Chili adds more heat for those who like mishkak spicy |
| oil | olive oil | same amount, 30 ml | Olive oil adds flavor, and any neutral vegetable oil works well over charcoal |
| Ingredient | 1/2 quantity | Quantity (base) | Double |
|---|---|---|---|
| Beef | 350 g | 700 g | 1400 g |
| Tamarind paste | 15 g | 30 g | 60 g |
| Crushed garlic | 7 g | 15 g | 30 g |
| Oil | 15 ml | 30 ml | 60 ml |
| Salt | 2.5 g | 5 g | 10 g |
A long marinade is the secret. We leave the meat in its marinade for at least two hours or a whole night, for tamarind and acidity tenderize the meat, and we grill it quickly over high heat so it does not dry out.
