[header] How to get rid of the whitefly [title] Vacuum the flies. [step] Use a small hand vacuum, or hold the furniture-cleaning nozzle of a standard vacuum cleaner.

[header] How to cook bay scallops [title] Have the rest of your meal, including the sauce, already cooked and ready to go. [step] Scallops taste the best the moment they are done cooking.

[step] It will feel like a tough spot on the side of the scallop, with the tissues running horizontally instead of vertically. (B) In addition, they'll become soggy when you're ready for the pasta, so it's best to bring them all out at once so they don't burn. [title] Read the instructions on the package of mascarpone.
