Understanding 100 Grams: Shelled vs. In-Shell
When you ask "How much is 100 g of pistachio nuts?" the first thing to consider is whether the pistachios are shelled or still in their shells. This distinction dramatically affects the amount of edible nut you receive and the nutritional value per 100 grams.
Shelled Pistachios: The Kernel Weight
For 100 grams of shelled pistachios, you are getting pure, edible kernel. This is the weight that all standard nutritional information, including calorie counts, is based on. A single 28g (1 oz) serving is about 49 kernels, meaning 100 grams of shelled pistachios represents roughly 3 to 3.5 individual servings and contains approximately 180 to 200 kernels. This is the most calorie-dense form of the nut per gram.
In-Shell Pistachios: Accounting for the Shell
If you purchase 100 grams of in-shell pistachios, a significant portion of that weight is the inedible shell. Studies indicate that the kernel or nutmeat makes up only about 48 to 50 percent of the total weight of an in-shell pistachio. This means 100 grams of in-shell pistachios will only yield 48 to 50 grams of edible nutmeat. The act of shelling them also slows down the eating process, which is often recommended by nutritionists for better portion control and mindful eating.

Recipe Idea: Simple Pistachio and Herb Pesto
Ingredients:
- 100g shelled pistachios
- 2 cups fresh basil leaves
- 2 cloves garlic
- 1/2 cup extra-virgin olive oil
- 1/2 cup grated Parmesan cheese
- Salt and pepper to taste
Instructions:
- Toast the pistachios lightly in a dry pan until fragrant. Let them cool.
- Combine the cooled pistachios, basil, and garlic in a food processor. Pulse until coarsely chopped.
- With the processor running, slowly drizzle in the olive oil until the mixture is smooth but not completely uniform.
- Add the Parmesan cheese and pulse a few more times. Season with salt and pepper.
- Serve immediately with pasta or store in an airtight container in the refrigerator for up to one week.
Making Your Own Homemade Pistachio Cream
Instructions:
- Blanch the pistachios: Boil 100g of raw, shelled pistachios for 1-3 minutes. This helps loosen the skins.
- Remove skins: Drain and immediately plunge into a bowl of ice water. Place on a clean kitchen towel and rub vigorously to remove the skins. Discard the skins.
- Process into a paste: Place the blanched pistachios in a food processor. Blend for an extended period, scraping down the sides as needed. It will first become a powder, then a thick paste, and finally, a smooth, oily cream as the natural oils are released.
- Add flavor (optional): For a sweeter cream, add a splash of milk and icing sugar to the paste before it becomes fully liquid. For a rich dessert cream, melt white chocolate and add it to the final pistachio cream.
