Gently warm your salted butter with fresh rosemary sprigs for 5-10 minutes before brushing to extract maximum flavor and create an aromatic compound butter that penetrates the rolls.

Lightly toast fresh rosemary leaves in a dry pan for 30 seconds before chopping and sprinkling to intensify their woodsy notes and prevent them from tasting too raw or grassy.

Apply coarse sea salt to the butter-brushed rolls immediately after brushing, while the butter is still warm and slightly wet, so it adheres perfectly and creates a delightful textural contrast.

Brush the rolls with rosemary butter within 2-3 minutes of removing them from the oven while they're still hot, allowing the butter to absorb into the soft interior and release the rosemary's essential oils.

Apply a second, lighter coat of rosemary butter after the first coat has slightly set for added richness and a more pronounced herbal flavor without making the rolls greasy.
