Engine start overtemp. First day back to work after 1 month off for vacation, wedding etc. During left engine start at bog, after introducing fuel, realized that I should have waited for 10% N2 (high altitude procedures) but had actually introduced fuel at about 7% N2. Decided to keep a close eye on egt during start. Egt rising very slowly as engine approached 50% N3. Egt appeared to be peaking, but continued slow rise. As it approached 570 degrees egt limit, cut fuel, but too late. Egt peaked at 575 degrees and was above 570 degrees for a total of 1.4 seconds. Motored engine for cooling and returned to gate for maintenance inspection.
