Income Taxes	6 Months Ended

Income Tax [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We are subject to U.S. federal income tax as well as income tax of multiple state jurisdictions. The tax years prior to our fiscal year ended April 3, 2016 are closed to examination by the Internal Revenue Service, and with few exceptions, state and local income tax jurisdictions. Our effective tax rate for the six months ended September 29, 2019 was 26.3% and was 27.0% for the six months ended September 30, 2018. The effective tax rate is impacted by projected levels of annual taxable income, permanent items, and state taxes. As of March 31, 2019, our balance sheet included a long-term liability for uncertain tax positions of $0.1 million, which arose from tax positions taken by Stauber Performance Ingredients, Inc. (“Stauber”) on its tax returns for periods prior to our acquisition. Because the Stauber acquisition agreement provides us with indemnification by the prior owners for any tax liabilities relating to pre-acquisition tax returns, we have also recorded an offsetting, long-term receivable of $0.1 million as of March 31, 2019. As a result, any change in the unrecognized tax benefit will not impact our effective tax rate in future periods. As of September 29, 2019, the long-term liability for uncertain tax positions and the offsetting long-term receivable have been removed from our balance sheet, due to the expiration of examination periods for the relevant taxing authorities.
