Parmesan pink clams (machas) are a typical Chilean dish made with clams, a saltwater bivalve native to Chile known scientifically as “Mesodesma Donacium,” and Parmesan cheese.

## Nutrition Facts

Each serving of Parmesan Pink Clams (approx. 5–6 prepared shells) contains approximately 240 kcal, 18 g of protein, 14 g of fat, 6 g of carbohydrates, 85 mg of cholesterol, and 480 mg of sodium.

## How to Make Parmesan Pink Clams

The inner flesh of pink clams is gray when raw but turns pink when cooked, undoubtedly one of the most cherished dishes for Chilean or foreign visitors to the northern region.

**Prep Time:** 30 minutes

**Cook Time:** 15 minutes

**Servings:** 6

### Ingredients

- 50 cleaned pink clams
- 30 clam shells washed
- 100 g of melted butter
- 1 ½ cups of creamy cheese
- ¾ cup of Parmesan cheese
- 100 ml of white wine
- 6 lemons
- Sea salt
- Pepper

### Instructions

1. Open the fresh clams with a knife by separating the shells. Remove the shells from the base with a sharp knife and set them aside. Thoroughly wash half of the shells, removing any sand or impurities. Remove the interiors of each clam tongue and wash them very well.
2. Turn on and preheat the oven to 200°C (396°F) for at least 10 minutes. Place one clam in each shell (two if they are very small) on a baking tray. Cover each clam with a pinch of salt, a teaspoon of white wine, a teaspoon of butter, creamy cheese, grated Parmesan cheese, and a dash of pepper.
3. Place in the preheated oven and cook for about 5 minutes until the clams are pink and the cheese has melted. Remove and serve the Parmesan clams immediately with a good chilled Chardonnay, accompanied by lemon halves for squeezing.

## Expert Cooking Tips

- **Flash Gratinating at High Temperature:** Preheat your oven to a high 200°C (396°F). This temperature is high enough to induce the Maillard reaction on the Parmesan cheese, creating a savory, golden-brown crust, while the short duration prevents the clam “tongue” from becoming rubbery or shrinking.
- **Strategic Acid Deglazing:** Add exactly one teaspoon of white wine to each shell. As the wine boils inside the shell, it deglazes the juices of the clam and emulsifies with the melting butter and creamy cheese. This creates a small, concentrated “beurre blanc” style sauce right inside the shell.
- **Bivalve Cleaning Precision:** Ensure you remove the dark “interiors” of each clam tongue. This is essential for a clean, sweet flavor profile. Any remaining sand or digestive tract can introduce grit or bitterness that ruins the delicate balance of the cheese and wine.

## Frequently Asked Questions (FAQ)

### 1. What is the difference between “creamy” and Parmesan cheese here?

The creamy cheese (like Mantecoso or Gouda) provides the melt and “stretch,” while the Parmesan provides the saltiness and the crispy crust.

### 2. Can I use pre-frozen clams?

Yes, but ensure they are fully thawed and patted dry. Frozen clams release more water, so you may need to drain the shells slightly halfway through to prevent the cheese from “boiling” instead of gratinating.

### 3. Why do the clams turn pink?

This is a natural chemical reaction to heat. The gray pigment breaks down, revealing the vibrant pink/orange tones underneath.

### 4. How do I keep the shells from tipping in the oven?

If you don’t want to use salt, you can “scrunch” a piece of aluminum foil on the baking tray to create “nests” for each shell to sit in.

## Parmesan Pink Clams in Clay with Cream

One of the most common variations of Parmesan clams is to prepare them in a base of sautéed onions, to which about 200 ml of cream is added until it thickens. Then, distribute them in clay dishes, covering everything with Parmesan cheese and finishing the cooking in an oven at 200°C for 15 minutes.

## Did You Know?

Clams are harvested along the entire Chilean coast using a process that can be quite unique, as harvesters locate them by feeling their feet sink into the wet sand.
