Spencer Gulf Prawns 16/20: Size, Prep and Cooking Guide

Short answer: The 16/20 size indicates roughly 16 to 20 whole prawns per kilogram, giving substantial pieces that are well suited to grilling, steaming and centre-of-plate presentation.

Because the shell protects the flesh and contributes flavour, the most reliable method is to cook the prawns whole and remove the shell at the table or immediately before serving.

Key takeaways

• Expect roughly 16–20 whole prawns in the 1kg pack.
• Keep the shell on for grilling or steaming unless the recipe requires peeled meat.
• Cook only until the flesh is firm and opaque.
• Dry the surface before high-heat cooking to improve colour and reduce steaming.

Why does the Spencer Gulf Prawns Whole (16/20) - Australia 1kg format matter?

Size codes are count ranges rather than exact lengths. The lower the count per kilogram, the larger each prawn. This pack is therefore designed for visible presentation rather than tiny chopped pieces.

How to prepare and cook whole prawns

1. 1. Keep the pack chilled until the rest of the meal is ready.
2. 2. Rinse only if the current pack instructs it, then pat the shells thoroughly dry.
3. 3. For easier eating, cut along the back and remove the dark intestinal tract while leaving the shell attached.
4. 4. Season lightly with oil, salt and lemon zest; avoid a long acidic marinade.
5. 5. Grill, pan-cook, steam or boil according to the pack instructions, turning once where appropriate.
6. 6. Stop when the flesh is firm and opaque, then rest briefly and serve with lemon.

Which pairings keep Spencer Gulf Prawns Whole (16/20) - Australia 1kg in focus?

• Lemon and parsley sharpen the sweet shellfish flavour.
• Garlic butter is useful for grilling but should not burn.
• Saffron rice turns the prawns into a complete main course.
• Aioli gives a rich dip; serve in a separate bowl.
• A crisp salad keeps a large prawn portion balanced.

How should Spencer Gulf Prawns Whole (16/20) - Australia 1kg be portioned and timed?

At 16–20 prawns per kilogram, plan four to five pieces per guest for four people, or two to three each when the prawns share a larger seafood spread.

Cook prawns last. Have the platter, garnish and napkins ready because a delay after cooking continues to firm the flesh and reduces juiciness.

Which Spencer Gulf Prawns Whole (16/20) - Australia 1kg mistakes should you avoid?

• Confusing 16/20 with grams per prawn; it is a count range per kilogram.
• Cooking the prawns straight from a wet surface on a crowded pan.
• Leaving them in a hot paella or sauce for the entire cooking time.
• Using colour alone; shell colour varies, while opaque, firm flesh is the safer cue.
