Hi Orazio.
Welcome to the Scoolinary community!
It’s great that you’re taking Antonio Bachour’s course! If you’re making croissants in Florida without access to Rouge Viennoiserie flour, you can look for accessible alternatives with similar characteristics.
PL (the ratio of tenacity to extensibility) is not always mentioned on commercial flours in the U.S., as it is a more common parameter in French or Italian flours. However, based on strength (W) and protein content, here’s an estimated breakdown of how some popular U.S. flours perform:
1. King Arthur All-Purpose Flour (11.7% protein) → Estimated PL: ~0.5-0.7
This flour has good extensibility and elasticity, making it a decent choice for viennoiserie.
2. Gold Medal Unbleached All-Purpose Flour (10-11% protein) → Estimated PL: ~0.4-0.6
More extensible than strong, but manageable for laminated dough with good technique.
3. King Arthur Bread Flour (12.7% protein) → Estimated PL: ~0.7-1.0
Stronger flour, which may make the dough less extensible. If using it, I’d recommend mixing it with a softer flour (like pastry flour) to adjust the PL.
4. Bob’s Red Mill Pastry Flour (~8-9% protein) → Estimated PL: ~0.3-0.5
Very extensible but low in strength, which may result in a weaker croissant structure. It can be mixed with bread flour to balance it out.
Conclusion
If you’re looking for a PL close to 0.4-0.7, King Arthur All-Purpose and Gold Medal Unbleached All-Purpose are the best options available in Florida supermarkets. For more precision, you could mix one of these with bread or pastry flour depending on how the dough feels.
If you have access to specialty stores or bakeries that sell bulk flour, you could ask if they carry T45 or T55 bakery flour. In Miami, you might check out La Provence Bakery or other stores specializing in French pastry ingredients.
I hope this information helps.Best regards!
