Oh, that recipe text is definitely unusual — “oignons verts sucrés” (sweet green onions) in ice cream sounds more like a playful mistake than a real ingredient. Normally, a classic French-style crème glacée maison would use milk, cream, sugar, and vanilla — not onions! It looks like either a translation slip or a humorous twist.

Here’s how a corrected version of that recipe might look if you wanted a simple, creamy vanilla ice cream at home:

🍨 Crème glacée maison onctueuse (corrected)

• 500 ml de crème fouettée
• 250 ml de lait entier
• 100 g de sucre
• 1 sachet de sucre vanillé (or 1 tsp vanilla extract)

👉 Mix everything, churn in an ice cream maker (or freeze and stir every 30 minutes until creamy).
